Hey, how do i make an object(obj_rocket) move towards any object let's say obj_wall and then spawn something?
When my rocket reaches it's destination it just gets stuck and does nothing.
Another question how do i make my obj_rocket shoot towards obj_player but without following him, just to his direction.


Currently this is what i have :

Step event

move_towards_point(obj_wall.x,obj_wall.y,5)

Collision event

instance_create(obj_rocket.x,obj_rocket.y+40,obj_shoot)
instance_create(obj_rocket.x,obj_rocket.y+40,obj_shoot2)
instance_destroy()

Okay, for your first problem, you need to do a distance check between your moving object and the point it has to reach :

//STEP EVENT
if point_distance(x, y, obj_Wall.x, obj_Wall.y) > speed
{
move_towards_point(obj_Wall.x, obj_Wall.y, 5);
}
else
{
//SPAWN SOMETHING!
}

Now, for your other question, you need to tell your rocket when it is created what direction to go in :

//EVENT THAT CREATES THE ROCKET
with (instance_create(x, y, obj_Rocket)) direction = point_direction(x, y, obj_Player.x, obj_Player.y);

The "with()" function is very useful and is a great way of telling instances to run some code from inside another instance.

Minor typo...

Can't even make the first thing to work, my rocket just stays in 1 place.
More explanation please? What my speed should be? because i wasn't using speed, i was using vspeed for my rocket to go down.

EDIT : I just copied without looking, had to change < to > in step event
