Spawning off Screen move towards the center[SOLVED]

[Karrlem]

Hello all, I would like to know how to go about having enemies spawn outside of my room and move towards the center of the room.

CREATE EVENT:

x = choose(-random(100), room_width + random(100)); //Outside the left and right side of the room up to 100 pixels
y = choose(-random(100), room_height + random(100));

direction = point_direction(x,y,room_width/2,room_height/2);
speed = 2;

So basically what happens the choose() chooses either of the two values.

point_direction() starts from where enemy is, then points towards the center of the room

speed is used to set the speed of the enemy

That works perfect! Thank you soo much for the help!

I only got one question, I realized that it works properly but everything only spawns from the four corners of the screen. Do you know of a fix?

Sure, here is something that I tested and should work.

if irandom(1) == 0 {
    y = choose(-random(100), room_height + random(100)); //Come from either top or bottom
    x = random(room_width);
} else {
    x = choose(-random(100), room_width + random(100)); //Come from either left or right
    y = random(room_height);
}

Works! Thanks again!!
