how to reference to an objects coordinates using its id?

[chandleroca]

Hi so ive set that when my object (arrow) collides with another object (zombie) the arrow will get the zombies id. and store it in a variable named "store". But how do I use the id to locate the zombie. I want to make the arrow to be fixed into the collided zombie's coordinates.
I used this:

with (store)
{
// what should I put here???
}

If 'store' holds the id of the instance, you can simply use store.x and store.y to reference its coordinates.

ok ok lemme try it. Sorry im experimenting with basic codes and I just discovered about id's and "this. "

No worries.

FYI, you use 'with' to execute code as if from inside the instance you are referencing. You _could_ use that to get the coordinates, but it would be convoluted and not a good method at all.

If you would like that arrow to stick into the zombie only after it has collided, you can do something like:

In the arrow's create event, initialize store as noone.
We do this so we can use checks when working with the variable.

store = noone;

In the arrow's collision event with zombie:

if(store == noone){ //only want to stick to something if we have not stuck to anything else
  store = other;
}

In the arrow's step event:

if(store != noone){ //stick to an object only if we have actually collided with something
  x = store.x;
  y = store.y;
}
