Понятия не имею, почему происходит сбой моей программы. Я примерно знаю, где он падает, и это все. Код ниже и должен добавить чистый спрайт (1 & times; 480 px) и удалить врага, которого он поражает, если таковой имеется. Код:
-(void)gunManAttack:(ccTime)dt {
int avalibleSpace = 210;
int minY = gunShot.contentSize.height/2;
int maxY = avalibleSpace - gunShot.contentSize.height/2;
int rangeY = maxY - minY;
int actualY = (arc4random() % rangeY) + minY;
int aOa;
BOOL allowAttackGun = YES;
NSMutableArray *enemiesToKill = [[NSMutableArray alloc] init];
gunShot.position = ccp((gunShot.contentSize.width/2), actualY);
[self addChild:gunShot];
CGRect gunShotRect = CGRectMake(
gunShot.position.x - (gunShot.contentSize.width/2),
gunShot.position.y - (gunShot.contentSize.height/2),
gunShot.contentSize.width,
gunShot.contentSize.height
);
for (CCSprite *enemy in allEnemies)
{
CGRect enemyARect = CGRectMake(
enemy.position.x - (enemy.contentSize.width/2),
enemy.position.y - (enemy.contentSize.height/2),
enemy.contentSize.width,
enemy.contentSize.height
);
if (CGRectIntersectsRect(gunShotRect, enemyARect) && allowAttackGun == YES)
{
[enemiesToKill addObject:enemy]; //Add to enemiesToKill array (clean up array [enemies])
money = money + 100; //Add money for the kill
[moneyL setString:[NSString stringWithFormat:@"$ %i", money]]; //Update the money on the screen
aOa = 1; //Tell the aOa, the enemy was in the walking array
allowAttackGun = NO; //Prevent mutliple enemies from being killed (telling the program the attack has been completed)
}
}
for (CCSprite *enemy in attackingEnemies)
{
CGRect enemyARect = CGRectMake(
enemy.position.x - (enemy.contentSize.width/2),
enemy.position.y - (enemy.contentSize.height/2),
enemy.contentSize.width,
enemy.contentSize.height
);
if (CGRectIntersectsRect(gunShotRect, enemyARect) && allowAttackGun == YES)
{
[enemiesToKill addObject:enemy]; //Add to enemiesToKill array (clean up array [enemies])
money = money + 100; //Add money for the kill
[moneyL setString:[NSString stringWithFormat:@"$ %i", money]]; //Update the money on the screen
aOa = 2; //Tell the aOa, the enemy was in the walking array
allowAttackGun = NO; //Prevent mutliple enemies from being killed (telling the program the attack has been completed)
}
}
//Removing enemies from arrays
for (CCSprite *enemyType1 in enemiesToKill) {
if (aOa==1) { //If the aOa is 1 (aka the enemy is in the walking array)
[allEnemies removeObject:enemyType1]; //Remove the enemy from the allEnemies (walking) array
}
if (aOa==2) { //If the aOa is 2 (aka the enemy is in the attacking array)
[attackingEnemies removeObject:enemyType1]; //Remove the enemy from the attackingEnemies (attacking) array
}
[self removeChild:enemyType1 cleanup:YES]; //Then remove the element from this array (due to the fact it has alredy been removed from the other arrays)
}
[enemiesToKill release];
[self removeChild:gunShot cleanup:YES];
}
Отладчик выводит это:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString contentSize]: unrecognized selector sent to instance 0x80b7450' ***
Как я могу узнать, где происходит сбой?
