smart thinking. It looks fine with me when I dont do it, and when I do what you say, it is VERY high.

Was that @Me?

If so - well, it depends upon your character scale vs world-scale. For mine, I'm using: position camera camx#, camy#+20, camz# which keeps me to a pretty good scale. IE, when I'm standing in front of an identical character and looking level, I'm approx. looking that character in the eye.

Without it, I'm looking at their toes.

Great tut! When is gravity and AI going to be done?

By the way, is it possible to load an X model file and use that instead of spheres and boxes?

Life is like a box of chocolates, you never know what your going to get, your life however, is like a box of ACTIVE GRENADES!

@Possible: Ah good point . The height we set the camera at doesn't really matter right now since we dont have dynamic models in, but I'll fix that aspect.

To those that don't know how, just change the y positioning of the camera to

OBJECT POSITION Y(1)+<amount>

Substitue <amount> for the height you wish from the bottom of the player, a good standard for now is to use the player's y size divided by 2, making it right in the center of the sphere.

It's up to you if you want to change aspects like this, it doesn't make much difference but experiment with it.

P.S: Using the @ symbol and then the user's name specifies you're replying to them.


@Karb: Using .x models is perfectly fine for this, go ahead and try it. You might need to scale things a bit though.

Ok, I know I said I was back a week ago, but then I had to go to my grandfather's for a week (suddenly), so I couldn't get back to work. The tutorial will be going slower than it was when it began especially since I havent been programming for...3 weeks or so, but I'll try my best as usual.

This is a great tutorial, I've only just seen it. I was planning on making a FPS and now this has helped understand things like INTERSECT OBJECT and JUMPING much better. Thanks very much Can't wait 'till the gravity section!

Alright just incase people are waiting ive decided im not continuing with the tutorial until I have more time on my hands because things keep coming up and with school coming up along with a job and a girlfriend, I just dont have time.

Ill finish this when I can and post a finished file but just try doing it yourself, just some pointers for gravity:

Gravity Tips:

- Check if the user is on the ground (using intersect object)
- If the user isn't on the ground, move them down at a variable
- Increase the variable at which they move down as they move down for physics
- Disallow them to jump when theyre falling
- When they touch the ground, stop falling

AI Tips:

- Have the enemy turn right constantly until they see the user
- When the see the user (check if they do using intersect object or newxvalue and newzvalue commands), move the enemy forward and run through the enemy shooting process (reducing the users health)
- When the enemy is no longer looking at the user stop moving and start turning more to find them

- For added AI have the system check if the enemy is shot and if so make the enemy turn around and shoot the user



Deeply sorry but I really have no time to do any programming right now so, goodluck.

I look forward to you having time.

So deeply sorry for your loss. In the meantime I think someone should stickify this so it doesn't fall to the bottom of the threads and it doesn't die.

I agree...

So I have one thing to say to anyone who has just found this thread and that is that if your trying to skip ahead to read what has happened so far you might as well go back to the beginning and read ALL of it.

This is a tutorial not a walkthrough, it is meant to help you understand basic and advanced concepts that will also appear in other programs you later persue.

Without further ado a link to the first page.

Continuing to uphold the site by saying something of importance.

I think that part of making a game is learning the basics of programming. Here is a big tip. Learn to manipulate values to do what you want. Anything can be done in a game, you just have to pick the correct values and manipulate everything correctly and it should come out fine. Also keep in mind that the more variables in a project the more complex the project will be. If you find something like a FPS to difficult try something simple. All the guru's suggest pong, but I dont like it. Pong is good to learn how to create boxes and stuff but I think that any arcady kind of game like that will help.

Man, you don't konw how much this tutorial has helped me to understand DBPro!!! I'm reading the "Beginner's Guide to DarkBASIC Game Programming" while simultaneously working through on-line tuts and this tutorial has helped me to understand certain aspects of DBPro that the book has failed to help me fathom. Thanks Ruccus. You gotta continue!!!

I am trying to make the wall we created solid so that I can't pass through it, so I tried to make it so that if you interesected the object then the character would not move but I can pass straight through the wall. I removed the original coding so that you could only move foward or backward if you were interesecting with the wall and i was right. So, I was wondering how I could rewrite this code so that I cannot pass through the wall (Object 4).

`Movement Controls
IF KEYSTATE(17)=1 AND INTERSECT OBJECT (4, LIMB POSITION X(1,1), LIMB POSITION Y(1,1), LIMB POSITION Z(1,1), OBJECT POSITION X(1),OBJECT POSITION Y(1), OBJECT POSITION Z(1))>0 THEN MOVE OBJECT 1,0
IF KEYSTATE(31)=1 AND INTERSECT OBJECT (4, LIMB POSITION X(1,1), LIMB POSITION Y(1,1), LIMB POSITION Z(1,1), OBJECT POSITION X(1),OBJECT POSITION Y(1), OBJECT POSITION Z(1))>0 THEN MOVE OBJECT 1,0
IF KEYSTATE(17)=1 THEN MOVE OBJECT 1,.9
IF KEYSTATE(31)=1 THEN MOVE OBJECT 1,-.9
IF KEYSTATE(30)=1 THEN MOVE OBJECT LEFT 1,.6
IF KEYSTATE(32)=1 THEN MOVE OBJECT RIGHT 1,.6

Hey everyone thanks for keeping this thing alive, been getting back into programming so we'll see what happens!

As for collision, here's how I usually do it.

- Send out intersection rays in every direction of the user, (front back left right top bottom)
- If an intersection occurs and the intersection is right at the beginning of the intersection check, handle the collision appropriately.
- If you want a sliding collision feel as most developers do, you could check which intersection ray is being activated, and handle appropriately. So if teh user intersects on the left, move them to the right, front to back, top to bottom, etc.

I know thats not much help right now but Ill be getting back into programming soon (especially since Im taking a programming class - which I just so happen to be in now as I write - and programming games will impress the teacher )

I hope to reply back soon, glad this thing helped so many people.

yeah, i know what you mean...

i did a pong game using openGL and my teacher was like "YOU MADE THAT???????!!?!?!? "

(i probably should wait to show them anything too cool or they might have a heart attack...especially if i don't tell them it's in DBPro!!! )

New site dedicated to the tutorial is up, found at ruccus.net.

http://www.ruccus.net/Tutorial.htm

I also added two more chapters I believe, fairly small but I'm just getting back into it.

Also, I'll be posting the code on that site from now on instead of here.

Ruccus man,your tutorial has done the world for my rpg and my learning curve. Where do we send donations to?

Dont stop developing this. Maybe add some melee cobat code. Every FPS has a good knife fight or option to blugeon someone with a bat, bottle etc

maybe you adressed this in the tutorial but i haven't read it all yet

Go to www.RUCCUS.net/Tutorial.htm , it contains the entire tutorial, the current code, screen shots and an index for easy reference.

HOWEVER

I haven't added this recent chapter to the site since my computer's taken a turn for the worse on me, AND the current source code has some errors in it I've forgotten to fix. To get the current code just take the code from the above chapter at the end.

Site Updated A Lot

I revamped the last 3 chapters, edited them and corrected some major code problems that somehow slipped by me. I also edited Chapter 5 GREATLY, gave a more detailed explanation of DB's basic commands and collision theories, and altogether fixed everything. The new chapter is up featuring polygonal collision and I'll pick up tomorow, I have a half day of school so I should have some time to add a chapter.

Also, pretty soon I'll be releasing some media for download, just a heads u. It'll be a map file, a character, a gun, an enemy, the weapons, a HUD picture, other pictures, textures, some random objects like boxes and barrels, and possibly more. Not too soon but I'm just letting you know, duno why

Thanks for all the great comments so far, It's been helping a lot of people from what I understand.

P.S: Antidote thanks for the reminder on the variable definition, I'll be fixing that in the next chapter. As I said this is my first time making an FPS aswell

P.S.2: I'll be updating the website soon aswell (possibly even tonight) with a lot more resources for newcommers (a bunch of snippets, the tutorial will finally be features on the site, the forum will be back up, ad other things aswell). So, an all around productive week for ruccus.net is ahead!

Thanks

Glad to hear it.

I just read over the updates I did and there's a LOT of spelling mistakes, I can't fix them now because I'm at school but they'll be fixed by tonight for sure. I'm starting to think now that after I finish this I may do some sort of trilogy, Like the newcommers guide to creating RPGs and the newcommers guide to creating RTS's, maybe more like racing, sports games, I don't know the possibilities are endless.

<EDIT> Site's been edited, much less spelling mistakes and now it includes links to all of the collision examples given (except BSP and DBPs intersect object)
