Can we use (id) in if- else condition ?

Question

I have written my code in following way in cocos2d.

id actionTo = [CCFadeOut actionWithDuration:4.0f];  
id actionTo0 = [CCSequence actionWithDuration:2.0f];
if (m < enemyNumber)
    id actionTo1 = [CCCallFunc actionWithTarget:self selector:@selector(goToNextScene)];
else
    id actionTo1 = [CCCallFunc actionWithTarget:self selector:@selector(goToEndScene)];
id actionSeq = [CCSequence actions:actionTo, actionTo0, actionTo1, nil];
[targetE runAction: [CCSequence actions:actionSeq, nil]];  

error: expected expression before 'id'  

I am getting the above error. Should not we use (id) in if condition ? I want to get called two selectors by using the if- else condition. How can I make it ? Thank You.

Answer 1

You cannot declare new variable in that place. What you should do is declare your actionTo1 variable before if-condition and set its value there:

...
id actionTo1 = nil;
if (m < enemyNumber)
    actionTo1 = [CCCallFunc actionWithTarget:self selector:@selector(goToNextScene)];
else
    actionTo1 = [CCCallFunc actionWithTarget:self selector:@selector(goToEndScene)];
...

It's simpler to write

id actionTo1 = [CCCallFunc actionWithTarget:self selector:
                (m<energyNumber ? @selector(goToNextScene) : @selector(goToEndScene))];
