Hi guys

I've found a problem with CreateSprite, and checking and excluding piece of code I'm sute that it depends on this function.

I use LoadImage as argument for CreateSprite



when I draw sprite in a position, specified with SetSpritePosition, it's all ok, but there's another instance of the sprite in the top left corner (as you can see in the screen attached)! Any solution?

thanks so much!

Your for loop is loading the same image/sprite 9 times

Hi and thanks for your reply. I know it and I suppose it's not the problem. The loop is loading the same animation for 9 different entities, so it's right. I've discovered that CreateSprite load the sprite in 0, 0 position. I've solved the problem putting a SetSpritePosition with out of windows coordinates just after CreateSprite



in this way I've solved my problem but it's pretty strange and I'd like to know why this happen :/

It's normal behaviour. As soon as you create a sprite, it becomes a visible entity at the origin (0,0). You can do what you have done and move it off screen, or SetSpriteVisible to 0.

You should change the way you create your sprites. They can all share the same image instead of loading it 9 times and taking up 9x more memory.

actually slightly better to make them invisible - when you get lots of sprites you can really tell the difference but for most uses you won't really tell
also if you know a sprite wont have any physics or animation then using SetSpriteActive(sprID,0) helps fps
