iOS Sprite Kit why can't I repeat colorizeWithColor using white color?

Question

I\'m experimenting with ways of selecting sprite nodes using methods other than scale. The one method that I like the most is colorize with white, which highlights the node visi

Answer 1

This is very interesting - and I'm not sure I have the answer. Using a white colorisation does to affect a node differently from other colours.

if you perform a colorize on a sprite node with blueColor and watch in the simulator, the colour will remain.

[node runAction:[SKAction colorizeWithColor:[SKColor blueColor] colorBlendFactor:0.8 duration:0.6]];

However, if you perform a colorize on a sprite node with whiteColor and watch in the simulator, it appears to automatically unwind (even without any completion block).

[node runAction:[SKAction colorizeWithColor:[SKColor whiteColor] colorBlendFactor:0.8 duration:0.6]];

I can find no reference to why this might be the case in documentation/header files. Still searching.
