I'm working on a side scrolling beat'em up and I was wanting the buildings in the background to have randomized window and door placements. In other languages I could do this simply but defining an offset for each window or door and then drawing the image directly with the offset and building position. However in AppGameKit that type of functionality is being handled internally and positions can only be given to sprites themselves.

So when I generate a building would I need to create a set of sprites, keep track of which belong to a specific building, then iterate through them to update their positions in relation to the building?

you could use memblocks to "burn" the windows into each building.
this is some code i used to emulate the copyimage command (before i knew there was a copyimage() command haha)
i think it would be a good start to making something like you want

I hadn't thought of using a memblock! I'll play with it and report back. Thanks!



*EDIT*
First off I'm sorry for pretty much just stealing your line of code where you set the memblock data. Works like a charm as long as the x is positive. For my purposes I'm not too worried about getting it to work with negative x's for now.

Thanks again!

you're welcome. i'd love to see the results when it's finished!

if you run into performance issues you might want to try CopyMemblock() rather than a byte by byte copy

Off topic but is there an issue with CopyImage? I'm using it to pull apart a spritesheet that contains the building parts but occasionally it seems to fail or crashes the app.



*EDIT* Uploaded an image of what the game looks like right now. Currently the only thing decorating the buildings are the randomly placed doors. lol
It can actually scroll. There are three buildings and when one leaves the screen it assigns it a new randomly generated image to keep it from looking the same every time the building goes by.

Currently I'm running into an issue with CopyImage and my previous statement of it crashing the game is wrong. It just doesn't have any image data for whatever reason and it causes the building to be invalid. It seems to be random if CopyImage works or not for me.

CopyImage the command.


Most of the time it works but there are times where it seems like it just fails between multiple runs of the program without actual code changes.
