so I can't even math today. I am tinkering with a little game for my kids to quickly identify quantities (an early math skill). I have used the following code to create my sprites with a random color and position.



The problem is that sometimes the sprites cover eachother. I tried modifying it to test for collisions and rearrange, but its still not 100 percent.



I know that if I had to, I could type out a bunch of nested if's to do the job, but im sure there is a much more efficient way. I would like to use a "for i =" statement with the "if spritecollision=0" condition required before next i can happen. Thanks for the help in advance!

if anyone is interested in the game, its built with no supporting files in the media folder, just copy, paste and Run!

Also, as I am still learning the basics, I am completely open to any and all constructive criticism or feedback regarding my coding. Have a good day

do you need to organise sprites draw order via SetSpriteDepth()?

If I can get them to not touch at all then the overlap wouldn't be an issue. Honestly I kinda like the look of them overlapping a little, but the problem is if a 50x50 width sprite is placed, then a 100x100 sprite placed on top, the player will not count properly (and thats not fair x_x).

I apologize if I have misinterpreted your suggestion, but I'm not sure if that would help.

also, on a side note, anyone know if there is a way to generate simple sound bits using agk's language. just curious, for the sake of making an app without adding any media, if I can make a high pitch ding or buzz for a right answer, and a low pitch for a wrong answer. Thanks for the feedback Supertino!

This post has been marked by the post author as the answer.
Turn your screen into a grid (invisibly of course). Approach it like you would build an inventory system (or storage bag) in an RPG-style game. If you break the screen down into 16x16 grid squares, then flag which ones are occupied when a sprite is placed. Then when you randomly place the next sprite, ensure it has room to be placed there. If it doesn't fit, you have multiple options. Either repeatedly pick a new random position until it does fit (fine for a few sprite on a large area, but too many could potentially cause an infinite loop) or you do something more intelligent like shift the sprite over from that random spot until it does fit (less likely to cause an infinite loop)

The grid obviously puts a small limitation on positioning as you'd have to lock the sprite's location to the grid squares, but the severity depends on the size of the grid you choose.

Not much going on in work today, this is how I would do it, quick but functional.

Wow, Good stuff guys. Phaelax I think that is a good idea. Supertino, Its awesome that you would take the time to rewrite my program! I read through your code a little before bed last night, and it makes great sense. I see a ton of things that I could have done differently. Im going to take some time and rework everything using your code as a guideline. Thanks again!
