Spawning attack by player x and set y?

(1/1)

Hop:
So I am trying to create a boss attack that spawns a sword that shoots up out of the ground and then goes back down. I want it to spawn under the players current position and along the y access of the floor. So I set up an alarm that calls it like so.

if (instance_exists(objPlayer))
{
       var a = instance_create(player.x,y,objGLSword);

       alarm[0] = 100;
}

I'm not sure what to put for the y to make it at ground level and the game just crashes whenever the alarm goes off.

In the objGLSword object I just have the image speed set and then it deletes after animation end.

The crash report reads:

Fatal error in action number 1 of alarm event for alarm 3 for object objBoss

Push :: Execution Error - Variable Get 103930.player(100162, -2147483648)
at gml_objBoss_objAlarm3_1(line 3)- var a = instance_create(player.x,y,objGLSword);

Also how would I make it so the attack would only go off 5 or so times and then the alarm would stop resetting?

PS: I'm using yoyo's studio engine.

woopsies! there's a typo. in the instance_create, you accidentally put player.x instead of objPlayer.x

typos can get you, man!


P.S. any variables which are defined with var; code will disappear after the code ends, but if you drop the var; part and just define the variable then it'll stay permanent throughout the object.

P.S.S. making it happen 5 times can be done with a variable.
In the create event: amount=0;
In the alarm event:
if amount<5{
    amount+=1;
    alarm[0]=100;
    if instance_exists(objPlayer){
        var a = instance_create(objPlayer.x,y,objGLSword);
    }
}

and whenever you want the attack to happen again, just reset amount to 0.

Aelya:
y should be close to the room height, of course :p so 608 or a little more (so it actually spawns from below the room)

Thanks guys it works great now!
