我正在尝试在代码中加载几个大模型并显示场景。通常，加载和在屏幕上显示场景需要很长时间，因为它需要从 pod 模型中提取大量资源。所以，我想在主线程中填充第一个场景，并将其他场景留在单独的线程中。但是，当我将部分代码移动到单独的线程中时，它会崩溃。这是我的示例代码：
-(void) loadFirstScene
{
CC3PODResourceNode* podRezNode = [CC3PODResourceNode nodeWithName: @"FirstModel"];
podRezNode.resource = [IntroducingPODResource resourceFromFile: @"FirstModel.pod"];
podRezNode.shouldCullBackFaces = NO;
podRezNode.location = cc3v(0.0, -10.0, 0.2);
podRezNode.isTouchEnabled = YES;
[self addChild: podRezNode];
[NSThread detachNewThreadSelector:@selector(loadScenesInThread) toTarget:self
withObject:nil];
}
// Crashing if i add the below function in separate thread or background thread
-(void) loadScenesInThread
{
CC3PODResourceNode* podRezNode = [CC3PODResourceNode nodeWithName: @"SecondModel"];
podRezNode.resource = [IntroducingPODResource resourceFromFile: @"SecondModel.pod"];
podRezNode.shouldCullBackFaces = NO;
podRezNode.location = cc3v(0.0, -10.0, -5.0);
podRezNode.isTouchEnabled = YES;
[self addChild: podRezNode];
podRezNode = [CC3PODResourceNode nodeWithName: @"ThirdModel"];
podRezNode.resource = [IntroducingPODResource resourceFromFile: @"ThirdModel.pod"];
podRezNode.shouldCullBackFaces = NO;
podRezNode.location = cc3v(0.0, -10.0, -5.0);
podRezNode.isTouchEnabled = YES;
[self addChild: podRezNode];
// .. do more
}
有人可以指导我如何处理这种情况吗？
