Question

Hi every one well I’m on cocos2D and here is my code:

target.position = ccp(actualX, 0);

But I would like to add a random position like:

arc4random() / (UINT_MAX/2);

switch(position) {
    case 0: /* top */
         target.position = ccp(actualX, 200);
        break;;

    case 1: /* bottom */
         target.position = ccp(actualX, 100);
        break;

How can I do it please ? sorry for my english I’m french :/

Answer 1

Just get a random number between 0 and 3, and then apply your cases to each one of the cases, like below:

int positionCase = arc4random() % 4;

switch(positionCase) 
{
    case 0:
         target.position = ccp(actualX, 0);
        break;

    case 1:
        target.position = ccp(actualX, 200); 
        break;

    case 2:
         target.position = ccp(0, actualY); 
        break;

    case 3:
         target.position = ccp(200, actualY);
        break;
}
