多年来,我一直在努力让它发挥作用。我搜索了所有网络,只能找到错误。
这是我在 HelloWorldScene.m 中初始化函数的代码
- (id)init
{
// Apple recommend assigning self with supers return value
self = [super init];
if (!self) return(nil);
// Enable touch handling on scene node
[self setUserInteractionEnabled:YES];
[self setMultipleTouchEnabled:YES];
self.exclusiveTouch = NO;
self.claimsUserInteraction = NO;
// Create a colored background (Dark Grey)
CCNodeColor *background = [CCNodeColor nodeWithColor:[CCColor colorWithRed:0.2f green:0.2f blue:0.2f alpha:1.0f]];
[self addChild:background];
//Physics rules -- (Must go under [self addChild:background])
_physicsWorld = [CCPhysicsNode node];
//Sets the gravity of the world.
_physicsWorld.gravity = ccp(0,0);
_physicsWorld.debugDraw = YES;
_physicsWorld.collisionDelegate = self;
[self addChild:_physicsWorld];
//End Physics Rules
// Add a sprite
_player = [CCSprite spriteWithImageNamed:@"ship.png"];
[_player setScaleX: .2f];
[_player setScaleY: .2f];
_player.position = ccp(110, self.contentSize.height / 2);
_player.physicsBody = [CCPhysicsBody bodyWithRect:(CGRect){CGPointZero, _player.contentSize} cornerRadius:1]; // 1
_player.physicsBody.collisionGroup = @"playerGroup"; // 2
_player.physicsBody.collisionType = @"playerRect";
[_physicsWorld addChild:_player];
playerDirection = @"none";
// Create a back button
CCButton *backButton = [CCButton buttonWithTitle:@"[ Menu ]" fontName:@"Verdana-Bold" fontSize:18.0f];
backButton.positionType = CCPositionTypeNormalized;
backButton.position = ccp(0.85f, 0.95f); // Top Right of screen
[backButton setTarget:self selector:@selector(onBackClicked:)];
[self addChild:backButton];
// done
return self;
}
这是我的实际多点触控代码
-(void) touchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
CGPoint touchLocation = [touch locationInView:[touch view]];
touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];
CGPoint targetPosition = ccp(self.contentSize.width, _player.position.y);
if(touchLocation.x <= 350 && touchLocation.y >= 150){
playerDirection = @"up";
}
if(touchLocation.x <= 350 && touchLocation.y <= 150){
playerDirection = @"down";
}
bulletsOnScreen++;
if(touchLocation.x >= 351){
CCSprite *projectile = [CCSprite spriteWithImageNamed:@"black.jpg"];
[projectile setScaleX:.03f];
[projectile setScaleY:.03f];
projectile.position = _player.position;
[self addChild:projectile ];
CCActionMoveTo *actionMove = [CCActionMoveTo actionWithDuration:1.5f position:targetPosition];
CCActionRemove *actionRemove = [CCActionRemove action];
[projectile runAction:[CCActionSequence actionWithArray:@[actionMove,actionRemove]]];
}
我只想能够同时移动和开火?任何帮助,将不胜感激。谢谢!
最佳答案
目前正在使用 touchBegan 但请尝试 -
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
代替
-(void) touchBegan:(UITouch *)touch withEvent:(UIEvent *)event
