当我点击添加CCSPrite的Action方法时,这段代码会产生错误,钩子和我覆盖Hook以绘制附加到钩子的一行。
-(void)Action
{
// Create the hook
Hook *hook = [Hook spriteWithTexture:[[CCTextureCache sharedTextureCache] textureForKey:@"hook2_small.png"]];
hook.position = ccp(self.fishToCatch.position.x, self.fishToCatch.position.y - 10);
[self addChild:hook];
// Create appropriate move and move finished actions for hook and fish
id fishMove = [CCMoveTo actionWithDuration:0.5 position:ccp(200, 433 - self.fishToCatch.contentSize.height/2)];
id fishMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)];
id updateScore = [CCCallFuncN actionWithTarget:self selector:@selector(updateScore:)];
id hookMove = [CCMoveTo actionWithDuration:0.5 position:ccp(200, 433 - self.fishToCatch.contentSize.height/2 - 10)];
id hookMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)];
// Run the actions
[hook runAction:[CCSequence actions: hookMove, hookMoveDone, nil]];
[self.fishToCatch runAction:[CCSequence actions: fishMove, fishMoveDone, updateScore, nil]];
[[SimpleAudioEngine sharedEngine] playEffect:@"splash.mp3"];
self.fishToCatch = nil;
}
Hook是CSprite,我覆盖了draw方法
@implementation Hook
- (void)draw
{
[super draw];
glEnable(GL_LINE_STRIP);
glLineWidth(1.0);
ccDrawColor4F(14.0/255.0,118.0/255.0,188.0/255.0,1.0f);
ccDrawLine(ccp(self.contentSize.width - 15, self.contentSize.height), ccp(253 - self.position.x,459 - self.position.y));
// ccDrawLine(ccp(0,0), ccp(100, 100));
}
@end
我看到的错误是
OpenGL error 0x0500 in -[CCGLView swapBuffers] 280
OpenGL error 0x0500 in -[CCGLView swapBuffers] 280

答案 0 :(得分:1)
glLineWidth()是一个OpenGL ES 1.1函数。如果您使用的是cocos2d 2.x,它可以解释OpenGL错误。您不能在OpenGL ES 2.0应用程序中使用OpenGL ES 1.1函数。
