Color change by SKAction?
skaction, sprite, sprite-kit
Solution
[SKAction colorizeWithColor:self.color colorBlendFactor:0 duration:3];
A `colorBlendFactor` of 0 means that the color takes no effect, ie the color values are multiplied with `colorBlendFactor` to compute the actual amount of color applied to each pixel. Change `colorBlendFactor` to 1 and you'll see the sprite being colorized.
Problem
I want to change the color of an SKSpriteNode by score. Its color should change smoothly so I tried to use an SKAction. But, the color doesn't change. ``` if (score > 20) { SKAction *changeColor = [SKAction colorizeWithColor:self.color colorBlendFactor:0 duration:3]; [self.sprite runAction:changeColor]; return; } ```
