The physics stops when i scale my sprite in a loop.

i have dynamic sprite

agk::SetSpriteSize(sprite,xsize,ysize);

When I update it the program freezes using

agk::Update(time);

Does any one know how to update a sprite size and not freeze the screen.

Are you changing the sprite size every loop?

A sample of the code you use might help.

+ Code Snippet


void RSPRITE::DISPLAYSPRITES2(int xcnt)
{
		float alist=tlist->GETTRANS(xcnt,positionsprite.curframe,lpos);
		float xsize=slist->GETSPRITEXSIZE(xcnt,positionsprite.curframe,lpos);
		float ysize=slist->GETSPRITEYSIZE(xcnt,positionsprite.curframe,lpos);
				
		if(listpositionsprite[lpos][xcnt].spritephysics==false)
		{
		agk::SetSpriteSize(listpositionsprite[lpos][xcnt].spritenum,xsize,ysize);
		}
		else
		{
			//agk::SetSpriteSize(listpositionsprite[lpos][xcnt].spritenum,xsize,ysize);
			//agk::Update(50);
		}
		
}

the commented code is what is not working

I think the problem is that, when you change the size of the sprite, the physics size and stuff change.

So, you should turn the physics on the sprite off before resizing it and the reset it to what you originally wanted it to be.

And remove the agk::Update call. That is unnecessary since it will all update at the next sync cycle.

How often do you call RSPRITE:

ISPLAYSPRITES2?

i call it every loop I might just leave scaling physics out of my program for know. Tell I get the rest of the program done. That will take a while. I still need to debug a-lot of stuff in my sprite engine so this is not a major issue.
