The royalty free and open source game engine jump pixel is released here!
To make your game simply make new media and create levels.
The included media is scrambled as i dont want copy cat games of my own.
I would be very happy if you credit the jump pixel engine and me cliff mellangard when creating games with this engine.

This fix is simply that it runs at constant 60fps again after doing all the syncing manually instead.

First peek of my work with an platformer framwork.
This is wath i have done so far in little less then a week.
If you want to see the editor let me know so will i do a video of it
Phaze 1 of the project.

Phaze 2 of the project.

Level load times pc VS android.




The plan is to do somekind of rick dangerous meets mario game ?
But with my track record of completing projects

I made a function for sprites as multi touch buttons you can find here.

Another project

Looks like a good start.

---

Iam trying to tell you guys that i get bored very fast
But a promise is that if i get bored with this so will i release the whole source code.
For free to use like my other projects

My main problem is that i have so many other things going on in real life ,that i simply get exhausted on to large projects very fast.

I thought a simple platformer is more fun and not so though as fake 3d projects

Its extremely early and all the art is simply placeholders while i build the framework.

---

I know how it is. I work hard to not switching projects. I have a whole bunch of started on projects. I find the best way to keep to a project is if you can work on it continuously. Preferably every day. And if you are not working on it, think about it. And when you come across a bug or something else that makes you not want to work on the project you need to do whatever you can to get past it.

---

Looks great. Are you using XML or a plain txt file for the editor?

---

It is as extremely simple as it could get
The editor code do i belive is 50 lines.
The whole game level is built on an simple array like this
map[160,20].
The map tiles is drawn with an single sprite and i use a blank dummy sprite for the physics collision.
It loads extremely fast on all my mobile devices,its alot simplier to draw alot of sprites for the map but is very slow to load.
The magic lies in he map drawing routine that draws it on screen,something i learned from my short java experience.

The biggest joy with agk is the experimentation for me

Here is an screenie of the editor.



You only use the arrow keys to move.
Space to show the tile selector.
mb left to select and place tiles.
mb right to delete.

Everything in the engine is extremely rough right now

Something i struggle with every day
I belive i have some kind of adhd but the illnes whas not invenetd when i whas i child

Edited...............
The last fix for today is that tiles and objects use there own layers also in the editor.
So now can i place objects on top of tiles etc.
I wanted to be able to also place tiles in the background in the mapper that is possible now.

---

Looks like cliff your building a tile engine also I think its fun as well as extreamly wear out your fingers.

---

Whas bored with coding and started to do some new basic tiles to be used in the huge temple/castle where we will run around in
They are still pretty simple as i will be able to change them easy later on.

Yes an very simple one
Yours are a bit more advanced

---

I really like the new tile artwork Really makes it pop. I think you should look into trying to remove those sharp lines, making the tiles fit better next to each other.

BTW, shouldn't the button be gray instead, and placed a little higher up?

---

I am still far from done with my engine though still need to import tmx tiled files into it I got it to parse the tmx files but I figuring how I want to display it. I also need animating lights, spot lights, and flickering lights. Might be too much for the undo and redo code might be done next year.

---

Thanks.
Yes i know that they dont fit perfectly right now,i wanted to do a batch that i can adjust when i get an overview on how it looks ingame.
The button and virtual jostick is simply place holders while i write the engine
Neaded them when testing on my 3 android devices

One reason i also get lines is that i use percentage scaling as iam trying to leave the virual resolution.
I dont like the black borders i get with it!


Iam trying to keep my own simple so i dont get bored to fast

---

Hi Cliff

I would very much like to see a video of the editor you are working on. All your work here looks great. Keep up the good work.

Dennis

---

Thanks dennis
Could you wait a couple of days as i started to rewrite some of the core parts that currently makes it crash until iam finished

I writing a entity library for all objects as iam using separate libraris for each object right now.

I did it like that while i whas testing.

I will put up a playable version with the first level as soon as its done so can you play around with the editor your self

---

Sounds great Cliff I look forward to it

Dennis

Phaze 2 of the project.


It also gives you a quick glimpse of the editor if you notice it

Iam having a hard time to get box 2d to work with an platformer?

Enemys get stuck and get weird speed ups on movement

Its still pretty early in the project.

And all gfx are place holders made by me during development.

---

I uploaded a new video to show the fast load times on mobile devices of the levels
Iam pretty happy with the speed it loads the levels as i use an samsung galaxy y with an 825 mhz cpu when testing this.

---

Quite nice so far

I don't use the built in physics in my game. All I do is check for contacts and then do the physics myself.

---

Thanks!
Its only the beginning of the project
I have so many plans for traps,secrets,elevators etc
I havent decided yet if he is going to be able to shoot?
And use grenades like rick dangerous?

A true pain to get it to work the same on pc and android
But i use impulse with a timed value that seams to work the same on pc and android now for movement.
The collision is weird some times to and whas a real pain.

But i started the project with box 2d in mind as i have never used it before
And i havent used agks particles before either.
Iam always after pushing my limits as a messy coder

I hope i get some more time for the project soon
Extremely much at work right now

---

That's looking good. Just like Digital Awakening I don't use the built in physics in my game. I tried using Box2D to begin with but I couldn't get the players movements to look and feel right, so I coded the physics myself.

---

Thanks

I can tell you that i have thought of abandoning box 2d a feew times

But it seams to work like i want now ?

Noticed you have updated your vikings clone thread also !
Going to take a look

---

The first ever playable early beta of my engine

I want some feedback on the player controls as i use box 2d for everything with movement and collision.

I think its pretty good now?

Time to finetune and add some more stuff.

Looking forward on your feedback

The keys are....

arrow keys left - right moves the player.
arrow key down makes him jump.
tab key switches betwen editor and game during play.(this only works when playing a level)
in editor controls.
space tile and entity selector.
return saves the map.
backspace deletes everything drawn on the map.
mb 1 draws the selection.
mb 2 erases

---

I've hard a quick play through. You've done a good job getting a tile based platformer to work with box2d. Did you use a circle object for the player character so he didn't stick to some of the tiles?

Why have you made down key jump? It would be more natural if jump was space bar. Also for the jump he only jumps to one height. Most platformers make the player jump lower if they just tap the jump button, and jump higher if they hold it in.

I haven't had time to try the editor yet but ill do that tomorrow.

---

Thanks! and it whas a pain to get right

I use an circle collision bound on all moving objects like player and enemys.

Box collision simply dont work at all.

When i beta test so do i play with one hand on the computer and hold the android phone with the other
I always test all changes on pc and android as a small change could work well on pc and not at all on android.

So i wanted single hand controls during the development
A good idea that i did not think of
I will test some things with how to use the impulse force for multi height jumping.

Its very plain but wath you delete and paint is selected with wath you select in the tile and entity selector screen.
If you click an tile so will you only paint and delete tiles.
if you click an action or entity so will you only delete and paint entitys and actions.

They use there own layers

Thanks for testing and feedback

---

Ok i added wath you wrote
quick tap on jump makes a small jump and holding the jump button makes him jump higher.
I also made a few other changes in movement.
replace the byc code in the download with this one.

---

Controls are far from optimal, they don't feel right and are a little glitchy here and there. But, considering you are using Box2D I am impressed. I never did try using circle collision sprites for my game. Is that why your character doesn't stick to walls in mid air, or did you use a different method?

Why not use up arrow to jump? You can still play with one hand.

---

Did you test with the latest bytecode i uploaded ?

The biggest problem is the jumping that i have partially solved by checking velocity. It is as simple as using a circle shape
Its no big deal right now as the game are for the mobile market with multitouch buttons

---

I have the latest bytecode.


I will not comment on the jumping then.

If you try walking into a wall, the player and screen starts to shake. If you are standing next to the wall and press against it, this doesn't happen.

If you are moving full speed in one direction and then change direction, it takes a while for the character to change.

---

I use raycasting to check if to use impulse or not if standing close to a wall.
And if you walk in to it with an high velocity so would the impulse give it a higher force the then the raycast check distance,and the player bounce out of reach of the raycast and it starts over.
Will see if i can make the check longer?
Its intended as one of my all time favorites works like that
Turrican on amiga and c64
I first made it like the standard way where the change is instant,but that feelt wrong also?
Mostly because the scrolling background made it look choppy also.

The jumping is a true pain and is still not finished.
Iam a physics noob and still learning it.
All feedback is neaded

Edited...........
Fixed the shaky background and player.
Took a while to pin down but it whas my code for changing the direction faster that made it,it uses reversed impulse force to change it faster.
Added a raycast check to it so it works now as it should.
Also added so both up and down arrow is the jump key

Will work on the jumping more tomorrow as its a huge bit harder to get right.

---

why do you not use polygonal shapes to check collisions? I did it in my platform game, and it works. It is very accurate, especially for characters without circular symmetry.

---

@CLIFF

hi. First postive comments....I like the graphic, did you draw them, what program you use. I just play for a little bit,seem to run smooth.

The bugs i found were:
1. when switch between editor and the game , will fast the player keeps falling until you at the bottom of screen and can not move. Then when I got into editor not show.

my Ideas:

When you in the editor is there any way to put a box outline on what tile you clicking.


EDIT : dont get bored on this project

---

Not played. I prefer my controls to be as accurate as possible. In RTA I use instant controls. It makes jumping on platforms very easy.

I check if my character is on the ground before pressing the jump button, otherwise it does nothing. I also check how long it is pressed. Adding a smaller and smaller boost the longer it is held. Until a maximum time is reached.

As you know there are others who have given up on using the physics for platform games

---

Iam trying to do it old school with physics and are doing it simple in the begining.
When i understand it better so will i try to advance

Its all original work by me as i have planned to release it later on and dont nead any copyright issues
Iam a sucker for pixel art but not that very talented at it,i can do some simple tile and sprites when iam in the mood for it.
I have bin messing on and off with sprites and tile art for over 20 years.
It makes me relaxed
Iam a sucker for paint shop pro by jasc software.
Corel messed it up when they bought jasc.
I have paint shop pro 5 fully boxed,paint shop pro 7 with only the cd left.
I found paint shop pro x on ebay that i havent tryed yet but i will soon.

I used my paint shop pro 7 version on this game.


The editor is so extremely rough
Did you change anything on the map?
Did you forget to draw the collider blocks? (white squares with an x in)
Did you forget to save your changes?

Could you post an screenie?

Wath is not showing in the editor?

A planned feature i havent simply done yet
I told you that iam lazy

No promises ! No promises

Iam having some problem with the physics get collision id
So iam simply forced to using raycasting until its solved.
I have an function that checks if the sprite is on ground but if i only used a simple collision check so did it miss to many times when i wanted to jump.
So it also uses raycasting for its check.
I use 2 impulses for the jump in its current state.
1 = simple short jump when the jump bt is tapped.
2 = check if the jump bt is still pressed after a specific distance gives another impulse so he jumps higher.
Probably one more soon

---

I think it's better to use SetSpritePhysicsForce for jumping. You can use it evey frame the player holds the button, but smaller each frame. That's basically how I do it, but I have my own physics code.

---

The problem with the jumping is that i use a single dummy sprite i add collision shapes to for the entire level.

Agk seams to be extremely bugged with getting collision if you added multiple collision shapes to a single sprite?

---

@ cLIFF

I guess the bug i found was an error i did. Th character wasnt spwaning in a with box with an X. I manage to find another error on my point...i put a spike one block atop af the AI and the program went crazy. everytime the AI hit the spike it would kill my playere in a loop cycle of dying. I tried taking a screenie but doesnt show, mite show as a video.

How you post videos on your post with having to go to youtubepage to watch. last time i tried to link all i could get was to post the link.

well you pixel art looks very cool and professinal, for example like the brick walls the are darker.... the programs you use never use them mite look into those. i did brought from TGC site was the ProMotiom version 5 which does pixel art.

heres one i did in promotion v5 for my game project while i learn agk.

---

I havent done it so user friendly yet
I recomend that you look at my map on how i did it to see how its done until i have fixed the editor some more.
I know about the spikes and its going to be fixed
+ Code Snippet

[youtube]videocode[/youtube]

Promotion is a very good paint prg
And thanks
I dont have it but think about buying it every day
The darker bricks are simply the bright ones i adjusted the brightnes on

---

The project is not dead

But lesson one!

Mobile devices do really not like draw sprite command

And its used alot!

Works very well on computer but as the project progressed and i added stuff to the engine,things started to get slow on android.

Have spent the last week trying to optimize the level render with no progress at all.

And are shifting to the multiple sprite method i used in boinkadroid that works.

But a huge load of work to rewrite everything.

With drawsprite so did the game drop to 16-25 fps sometimes when it drawed alot of tiles.

With a simple experiment where i simply shifted 200 sprites around for the tiles on screen so did i get 36-60 fps on android.

Time to optimize that method instead.

---

Is this when I say "I told you so"? Or maybe not to you, but I have said so in multiple threads by now

Good luck and keep fighting on!

BTW, how do you do physics without multiple sprites?

---

I dont remember ?
But it works very well to a specific limit where it starts to fail,so when i added more and more stuff so did it fail big time

Draw sprite have issues when sprites are visible on top of the sprite being drawn and such.
Its a great command when they work some more on it

I use an grid map and place a dummy sprite at grid 0,0.

Then do i read in the map array and use addspriteshapebox on that dummy sprite.

Very simple and works very well

But i have advanced this code some more to use less shapes .

Sorry for the wage post but iam really tired this weekend from an overload of work the whole week

---

Latest version of the framework.
The largest improvement is performance and i have added alot of things.
If the video dont show? Be patient as iam writing this while uploading
I whas extremely tired while recording this thats why i die so often ZZZZZZzzzzzzzzzzz.
