mesh->setFrameLoop() access violation

[pippy]

I have a scene::IAnimatedMeshSceneNode*. I want to change its animation according to what state it's in

i can call mesh->setFrameLoop() just after it has loaded, but if I call it at render time it gets an "access violation" and crashes

any ideas why?

I think you can use the bool variable to toggle the setFrame loop such as :
if (!active)
{
mesh->setFrameLoop();
active = true;
}
Maybe this way can help.

Thanks for your reply trivtn.

Using a boolean to set the frame loop would mean i could only set it once, and i want to change it twice

I found the problem, it was that mesh was undefined in some cases.

so

Code: Select all

		if(NULL != mesh){

			//what state you are in
			if(state != tmpstate){
				switch (state){
				case 0://idle
					mesh->setFrameLoop(myType->idle_start, myType->idle_end);
					tmpstate = 0;
					break;
				case 1://walking
					mesh->setFrameLoop(myType->walk_start, myType->walk_end);
					tmpstate = 1;
					break;
				case 2://attacking
					mesh->setFrameLoop(myType->attack_start, myType->attack_end);
					tmpstate = 2;
					break;
				case 3://attacking
					mesh->setFrameLoop(myType->attack_start, myType->attack_end);
					tmpstate = 3;
					break;
				default:
					mesh->setFrameLoop(myType->idle_start, myType->idle_end);
					break;
				}
			}
}
