POiPhone game development with Cocos2d: how to generate a cool light effect when an entity gets hit?
text
Body
copied!<p>Abused topic considering the posts (e.g <a href="https://stackoverflow.com/questions/7005188/how-to-light-up-a-sprite-in-cocos2d">this</a> or <a href="https://stackoverflow.com/questions/9492641/color-changing-sprites-cocos2d">this</a>) but I still don't quiet manage to get what I want. </p> <p>I am working on a shooter game and I would like to light up my enemies when they get hit (as well as the player). </p> <p>If I run the following my sprite doesn't get white. Is this the right direction?</p> <pre><code>-(void) gothitAnimation { ccColor3B originalColor = self.color; id delay = [CCDelayTime actionWithDuration:0.4f]; [self runAction:[CCSequence actions: [CCTintTo actionWithDuration:0.01f red:255 green:240 blue:240], delay, [CCTintTo actionWithDuration:0.01f red:originalColor.r green:originalColor.g blue:originalColor.b] , nil]]; } </code></pre> <p>I have tried running only the CCTintTo action and it does work only with colours different than white. </p> <p>I have found Arodius's game demo and it seem to me that there the player ship gets set multiple times to invisible and visible in a short sequence of actions when hit or in lower energy levels (see <a href="http://www.youtube.com/watch?v=-6fNQBt0Mio" rel="nofollow noreferrer">this demo</a>). Also the enemy get a light effect when hit.</p> <p>Any idea on how this has been achieved? Did the developer use the CCTintTo action or something else? I know that for the explosion he used ParticleEffects.</p>
