OK, real problem time, rather than me just flaming other peoples threads.

I was trying to learn the sprite commands at the weekend. Im fine with playing animation through the use of cutting out my images from my bitmaps then setting the image number on the sprite to the frame I want. However, then I looked at the play sprite command. This takes a bitmap and cuts it into frames for me, then plays those frames in a sequence.

Can I tell db to take those frames from an image rather than a bitmap? Or, how can I load my own sequence of images into the sprite?

Basically, Im trying to understand a way to get all the frames I want(at least 100 per charachter on screen) organised into the neatest and fastest code I can.

Any help would be good.

GIve me more power!

Well you can use the Load Image "YourSprite.bmp",1

It might need ......Load Image "YourSprite.bmp",1,1

Two ,1,1

I think that turns off AA, I'm not sure, because I don't have DBPro.
Then you can time your animations like this...


T=Timer() + 500......half a second, whatever you want

Do

If T<= Timer then

paste your sprites here!
T=Timer() + 500......half a second, whatever you want
Endif

Loop

So what yor`re saying is that I can load a bmp straight to an image rather than to a screen, then use that image with the play anim command?

How do specify that you want to use an image rather than a screen as the source for your "play sprite" command? Or can I just make all my frames as, say, 32x32 .bmp files than just load them all in as "images"? How many images can I use in DBpro, 6400?

Do this....

You can save your Image at their correct size..32*32..Whatever..
Say you name your Images....


MyImage1.bmp
MyImage2.bmp..........Then you can......


for n = 1 to 100

Name$ = "MyImage" + str$(n) + ".bmp"
Load Image Name$,n,1..........not sure about the second 1

next n

Now all of your images are given a number from 1 to 100 or however many images you have. Now you only need 1 sprite! But you keep changing its Image number in a loop. Make sure you time the change like I said earlier.

put all the images for 1 sprite into 1 sprite sheet, so for 100 images it would be 10x10
use
create animated sprite 1, "spritesheet1.bmp", 10, 10, 1
to cut up the sheet into frames
use
play sprite 1, 1, 100, 50
to start the frames in order 1 to 100
now your loop
do
use set sprite frame to select which frames you want to show( you don't have to show all 100 at a time, say you have 10 sets of 10 animation, thats fine.
use the sprite command to place the sprite as usual.
sprite 1, mousex(), mousey(), 1
loop

all 100 images loaded and looping in what 4 commands, is that compact enough, there is a bug with create animated sprite look,here
http://www.thegamecreators.com/?m=forum_view&t=14254&b=15

I have a work around for it for ,but since p5 it's not such a big problem , you may not notice it anymore.

Sounds good to me, I like the idea of having my images cut out before, as Ive been having problems sorting outthe order of cutting out sprites with commands, so loading all the images in is a better way for me I think.

Help with what?? if you have a problem let us know what it is

The one thing i noticed, i think this will be causing your animations to not show correctly:

n=9
sprite 1,100,100,n
sprite 2,100,160,n+16
sprite 3,100,240,n+24
sprite 4,100,320,n+32
sprite 5,160,100,n+40
sprite 6,160,160,n+48
sprite 7,160,240,n+56
sprite 8,160,320,n+64


sprite 1 = Image 9
sprite 2 = Image 25
sprite 3 = Image 33
sprite 4 = Image 41
sprite 5 = Image 49
sprite 6 = Image 57
sprite 7 = Image 65
sprite 8 = Image 73 <- does not exist

So you start with 8 sprites on the screen with sprite 8's image not existing.

You arent using images 17 -> 24 :- your first jump (n+16) should be (n+8)?

You also only move sprite 1 so why do you need 8 sprites?

When you stop moving and start running right, it will cycle through the 8 stand images (thats what i guess images 1 - 9 are) because:

rundir = 1
n = rundir

then when you move right n = n + 1
so it will go through all those images instead of the running right images. So you need a condition if n < 9 then n = 9

or something like that.

I havent run the program these are just things i noticed in the code.....i might be wrong.

But let us know what the problem is then we can help better

Er, sorry its me pateing up something Ive not cleaned up! I put 8 sprites in origionally to test the loading of the images, then "rem"ed out my workings! Anyway, Im now onto the joys of maps and walls. Ive got my map drawn in the back ground but cant seem to get any collisions working between the player and the back ground...

i'm not a mod but next time code stealer please post the code in a codebox, it's alot nicer for other people to read. also the loading image procedure could probably be better done with a loop and it wouldn't be so hard to load all those images, just a thought.

I cant seem to post code up as a snippet! It jsut doesnt apper if I put it in the box below....

Also, please can you explain how to make the loading of images into a good loop, how do you handle all the different filenames? Help with this sort of thing will really help my code! Thanks. Im working on a turn based strategy battle game at the moment and am going to have up to 4 players, who can choose an army from orcs, elves, human or dwarf, and can choose a colour out of 4 colours, so that each player can be the same race if they want to. Its going to be pretty simple graphics, but I need a good way to load in all the images into the correct slots, ie if player 1 chooses dwarves as his race and green as his colour, I want to load the green dwarf images into the image slots allocated to player 1. Just pseudo code will do, just to help me understand a bit better how to layout structured filenames.

The very first post I made to you was how to load animations in a loop. Here's 1 example.......

for n = 1 to 8

FileName$ = "uber_run_r" + str$(n) + ".bmp"

Load image Filename$,n+8

Next n

Ahh, Ok, thanks. Ill give it a try. I know it must be a simple routine, but its just getting the syntax right that causes the headaches!

I load 1 image that contains all my sprites and use code to grab the sprites from the single image. You can use a couple of for next loops and a get image or get sprite command to do this.

To me it's a little easier than having 100 sprite files. Plus I'm lazy...

No you don't Dim it because it is a Command, and not an Array.

Hmm at the moment Ive only got say 30 images but im sure its gonna grow alot larger. You thinks it worth looking at load one image and chopping into images Tapewormz?

also am i the only one who has problems with png's crashing dbc. Ive had 2 pngs go screwy now.

Well the 10 lines of code saved you 30 lines of loading...and if its going to grow...then it's obvious which is more efficient.

The only problem i can see is that all my graphics are different sizes. The only way round this is to a have multiple gfx bitmaps for the different sizes ie bitmap1 32x32, bitmap2 64x64 etc etc.

Well, thats just it, you can write a piece of code that loads the graphics, which is what Im doing. Im gonna use about 2000 frames(Im an animator so doing lots of frames is what Im good at!) so I wanted to write a routine that lets me load all the graphics for a charachter with just a couple of lines of code. Ive got it working too, so writing code to cut one image into many is probably just as hard or easy as writing code to load many images. Its just up to you to name them all sensibly....

Anyway, the reason I prefer the idea of using individual files that I load in is that my animframes can be different sizes, say for an explosion which starts small but gets bigger. Im using dbpro with rotations, so my collisions are going to be quite crude, so having control of the sprite size on a per anim frame level seems quite usefull to me.

Yeah, I think it's actually less code to load them in as images all seperated. There is also less waste of black 0,0,0. This consumes speed, and memory. Like cutting metal sheets, you will waste some metal from a large sheet, but can crop the pieces exactly around the edges, if you use lots of small sheets.
