Setting a delay on a "Create an Object"

Probably really simple, but I've spun my wheels on this for the past two hours with no progress.
It's a simple, if objLink collides with objRing, it creates objBolt, which moves towards objLink, all well and good. However, it shoots WAAAY too many. Is there a way to shoot one every second or two?

Alarms on your collision event with the linkObj

Need more explaining?

Like Xiphirx said use a delay timer. Either with alarm events or a variable that decreases every step.

In the step event:

Code: [Select]

if( delay_timer ){
     delay_timer -= 1;
}

at the point of collision with Link.

Code: [Select]

if( !delay_timer ){
      //create a bolt towards Link.
      delay_timer = 60; //assuming 30fps
}

using those codes in the step and collision events for the boundary (the area where when inside, you get shot at), it will shoot one, then stop. Any help?

Link is still in the area after getting shot at? And you have reset the delay_timer? And you are decreasing it again?

Yeah, you sure you included "delay = 60;" after creating the bolt?

Otherwise you might want to try something like

Step:

Code: [Select]

if (delayTimer > 0) { delayTimer -= 1;}
if (delayTimer <= 0 && collidedWLink = 1)
{
//Create bolt
delayTimer = 60;
}

Collision:

Code: [Select]

collidedWLink = 1;

//When link leaves:
collidedWlink = 0;

Re: Setting a delay on a "Create an Object"

I took a look at the Gamemaker help files and found this:

When the other object is not solid, the instance is not put back. The event is simply executed with the instance at its current position. Also, there is no second check for a collision. If you think about it, this is the logical thing that should happen. Because the object is not solid, we can simply move over it. The event notifies us that this is happening.

I assume that objRing is not a solid object and thus when Link stays collided no collision event is generated again, until they uncollide. Thus the best thing you can do is put this in the objRing step event and dumb the collision event.

Code: [Select]

if( !delayTimer && place_meeting(x,y,objLink){
     //Send the bolt.
     delayTimer =60;
}else if(delayTimer){
     delayTimer -= 1;
}
