改变CCNodeColor的颜色

Question

我设置了一个CCNode：

CCNodeColor *node = [CCNodeColor nodeWithColor:[CCColor colorWithRed:0.1f green:0.1f blue:0.1f alpha:0.0f]];
        node.position=ccp(0,0);
        node.name=@"zoomAlpha";
        [self addChild:node];

哪个有效。 而不是改变它的颜色/ alpha：

 CCNodeColor *nood=(CCNodeColor*)[self getChildByName:@"zoomAlpha" recursively:NO];
        if(nood)
        {
              //i got here with a nood , but color is not changed
             [nood setColor: [CCColor colorWithRed:0.6f green:0.3f blue:0.4f alpha:1.0f ]];
            return;
        }

为什么？

Answer 1

试试这个：

    [nood setColor: [CCColor3B colorWithRed:0.6f green:0.3f blue:0.4f alpha:1.0f ]];

OR

      [nood setColor: [CCColor4B colorWithRed:0.6f green:0.3f blue:0.4f alpha:1.0f ]];
