[SOLVED] How to call the -(void)update:(CCTime)delta method in Objective-C

How to call the -(void)update:(CCTime)delta method in Objective-C

Is there a way to call the -(void)update:(CCTime)delta method in objective-c? I know that (using sprite builder) I can create a scene and then have it be attached to a custom class so that when the scene is loaded through the CCBReader, the class's update method is automatically called.

I am now loading the scene through code without a custom class but would still like the update method to "start" (for lack of a better word.) Is there a way to do this?

Solution

Call scheduleUpdate from, for example, onEnter method.

[self scheduleUpdate];

However if you are using cocos2d-objc or cocos2d-spritebuilder version 3.0 or later, update: methods is scheduled automatically.

https://github.com/cocos2d/cocos2d-objc/blob/v3.0/cocos2d/CCNode.m#L1190

-(CCTimer *) schedule:(SEL)selector interval:(CCTime)interval repeat: (NSUInteger) repeat delay:(CCTime) delay
{
    NSAssert(selector != nil, @"Selector must be non-nil");
    NSAssert(selector != @selector(update:) && selector != @selector(fixedUpdate:), @"The update: and fixedUpdate: methods are scheduled automatically.");
