本文介绍了用 ccTouchesMoved 方法移动 CCCamera?(cocos2d,iphone)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!
问题描述
所以我得到了这个工作:
so I got this working:
-(void) ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *myTouch = [touches anyObject];
CGPoint location = [myTouch locationInView:[myTouch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
for( UITouch *touch in touches ) {
CGPoint touchLocation = [touch locationInView: [touch view]];
CGPoint prevLocation = [touch previousLocationInView: [touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
prevLocation = [[CCDirector sharedDirector] convertToGL: prevLocation];
CGPoint diff = ccpSub(touchLocation,prevLocation);
[self setPosition: ccpAdd(self.position, diff)];
}
}
我可以用手指移动图层,但我想移动 cccamera,但我对 cccamera 没有任何经验.
I can move the layer with my finger BUT i want to move the cccamera but i don't have any experience with cccamera.
谁能帮帮我?
非常感谢祝你有美好的一天
Thank you very much Have a nice day

推荐答案
这是我正在使用的……这个移动相机的实现是我在 cocos2d 论坛上找到的.
Here's what I'm using... this implementation of moving the camera is something I found on the cocos2d forums.
-(void) ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *myTouch = [touches anyObject];
CGPoint location = [myTouch locationInView:[myTouch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
for( UITouch *touch in touches ) {
CGPoint touchLocation = [touch locationInView: [touch view]];
CGPoint prevLocation = [touch previousLocationInView: [touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
prevLocation = [[CCDirector sharedDirector] convertToGL: prevLocation];
CGPoint diff = ccpSub(touchLocation,prevLocation);
[self setPosition: ccpAdd(self.position, diff)];
// Get the camera's current values.
float centerX, centerY, centerZ;
float eyeX, eyeY, eyeZ;
[self.camera centerX:¢erX centerY:¢erY centerZ:¢erZ];
[self.camera eyeX:&eyeX eyeY:&eyeY eyeZ:&eyeZ];
// Increment panning value based on current zoom factor.
diff.x = 2 * diff.x * (1+(eyeZ/832));
diff.y = 2 * diff.y * (1+(eyeZ/832));
// Round values to avoid subpixeling.
int newX = centerX-round(diff.x);
int newY = centerY-round(diff.y);
// Set values.
[self.camera setCenterX:newX centerY:newY centerZ:0];
[self.camera setEyeX:newX eyeY:newY eyeZ:eyeZ];
}
}
