我正在使用Cocos2d引擎,我遇到了一个奇怪的问题。
我有一个精灵。另外,我为该精灵有2个动画。我想在app加载时播放一个动画,然后在调用ccTouchevent后播放。
walkAnim = [CCAnimation animation];
dropAnim = [CCAnimation animation];
for( int q=1;q<12;q++){
[walkAnim addFrameWithFilename: [NSString stringWithFormat:@"walkforward_%.2d.png", q]];
[dropAnim addFrameWithFilename: [NSString stringWithFormat:@"drop_%.2d.png", q]];
}
action = [CCAnimate actionWithAnimation:walkAnim];
action.duration = 2;
id act = [CCRepeatForever actionWithAction:action];
[sprite runAction:act];
所以,我们在这里看到一个动画精灵。
[sprite stopAllActions]; //and here my torture begins
我尝试了许多创造动作的方法:
我试图添加另一个AnimateAction,试图替换当前的动画,但一切都会导致崩溃。
[action setAnimation:dropAnim];
和
CCAnimate* animat = [[CCAnimate alloc]initWithDuration:30 animation:dropAnim restoreOriginalFrame:YES];
和
id action = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:dropAnim]];
[player1 runAction:action];
崩溃发生在[CCAnimate actionWithAnimation:]
中+(id) actionWithAnimation: (CCAnimation*)anim
{
return [[[self alloc] initWithAnimation:anim restoreOriginalFrame:YES] autorelease];
}
谢谢!
要从其他方法启动操作,您必须保留操作例如:[操作保留];
答案 0 :(得分:0)
要从其他方法启动操作,您必须保留操作
例如:[行动保留];然后别忘了发布
-(void)create{
for( int q=1;q<12;q++){
[playerWalkAnim addFrameWithFilename: [NSString stringWithFormat:@"walkforward_%.2d.png", q]];
}
playerAction = [CCAnimate actionWithAnimation:playerWalkAnim];
playerAction.duration = 2;
[playerAction retain];
}
-(void)launch{
[player1 runAction:playerAction];
}
