【问题描述】:
我的问题是动画在精灵移动期间无法正常工作。 下面是我正在使用的代码
- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
[selSprite resumeSchedulerAndActions];
CGPoint touchLocation = [self convertTouchToNodeSpace:touch];
[self selectSpriteForTouch:touchLocation];
return TRUE;
}
- (void)selectSpriteForTouch:(CGPoint)touchLocation
{
CCSprite * newSprite = nil;
for (CCSprite *sprite in movableSprite) {
if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) {
newSprite = sprite;
break;
}
}
if (newSprite != selSprite) {
[selSprite stopAllActions];
selSprite = newSprite;
_MoveableSpritetouch = TRUE;
}
if(_MoveableSpritetouch==TRUE)
{
movement=0;
CGRect selRect=CGRectMake((SpriteX)-20.0,(SpriteY)-20.0,40.0,40.0);
if(CGRectContainsPoint(selRect, touchLocation))
{
[selSprite stopAllActions];
}
if((selSprite==MarshallCar)&& (!(CGRectContainsPoint(selRect, touchLocation))))
{
movement=1;
[self reorderChild:selSprite z:5];
NSMutableArray *MarshallCarWalkAnimFrames = [NSMutableArray array];
for(int i = MarshallCarTouchStartFrameIndex; i <= MarshallCarTouchEndFrameIndex; ++i) {
[MarshallCarWalkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"mcar_move_%d.png", i]]];
}
MarshallCarWalkAnim = [CCAnimation animationWithFrames:MarshallCarWalkAnimFrames delay:MarshallCarTouchFrameDelay];
walkMarshallCar = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:MarshallCarWalkAnim restoreOriginalFrame:NO]];
[selSprite runAction:walkMarshallCar];
}
}
}
- (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event {
if(gameState == TRUE){
CGPoint point = [touch locationInView:[touch view]];
point = [[CCDirector sharedDirector] convertToGL:point];
if (moveDifference.x>0)
{
selSprite.flipX = YES;
}
else {
selSprite.flipX = NO;
}
[selSprite setPosition:point];
}
}
-(void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{
movement=0;
if(selSprite==MarshallCar)
{
[selSprite setDisplayFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mcar_idle.png"]];
}
[selSprite pauseSchedulerAndActions];
}
移动的动画帧不是每次都在移动时播放,有时会播放,有时不播放。当您第一次触摸和移动精灵时,它会正常播放,但如果触摸另一个精灵然后再次移动前一个精灵,则不会播放移动动画。
有人知道为什么会这样吗? 请告诉我删除此错误的正确代码。 谢谢!!!
