Question

I have a CCRepeatForever action with a tag of 20. I call this:

  [player stopActionByTag:20];

Noting happens.

I call this:

  [player stopAllActions];

It stops. Any idea? The action is created like this and runs fine:

 CCRepeatForever *repeat=[CCRepeatForever actionWithAction:animate];
 repeat.tag=20;

 [player runAction:repeat];

update: i also tried setting animate.tag=21 and stopping that action by itself or in addition to the repeat action, but neither works.

Answer 1

This should work, I made a quick test with stopActionWithTag using CCRepeatForever and it stops it correctly.

I can only imagine two cases where it wouldn’t work:

1. You have more than one action with the tag = 20 running on the same object.
2. The object you send runAction to is a different object than the one you send stopActionByTag to.

The former is easy to check. If this code fixes your problem, you’re running multiple actions with the same tag on the player object:

while ([player getActionByTag:20]) {
    [player stopActionByTag:20];
};

The latter is rather unlikely but possible. One way to find out is to set a breakpoint on the runAction line and note the address of the player variable. Then set another breakpoint at the stopActionByTag line and compare that player’s address with the previous one. If they’re not the same, then that would be the problem.
