how do I make an enemy turn around before it falls of a edge?

I was also wondering the same thing

you could try putting little canvas' on the edges so that when the enemy touches them it turns around.

oh good idea Or a filled region to prevent lag :3

Code: Select all

if(CollisionFree("Event Actor",x,y+2)==0)
{
    //Turn around script here, Here's what it could be?
    ChangeAnimation(///);
    xvelocitty=-xvelocity;
}

Hope this helps
This might not work all the time; if there are actor that do not have the Collision State set to Disable (It's a function) and goes under the character, well it'll turn around as well

thank you thank you!

if you want the enemy to change sides also when he encounters an objects on the left/right (So he doesn't hit them)
simply change the line

Code: Select all

if(CollisionFree("Event Actor",x,y+2)==0)

to

Code: Select all

if(CollisionFree("Event Actor",x,y+2)==0||CollisionFree("Event Actor",x-2,y)==0||CollisionFree("Event Actor",x+2,y)==0)

Just trowing this in

Filled regions aren't a good idea for doing this because you will have to place them on every single platform that is to have an enemy on it.

Then, editing your game becomes much much slower. You'll find you have to change platform positions for all sorts of reasons to make your levels challenging yet playable.

One thing you can do is with a cloned platform, is collision>topside>platform>repeat no>
int twidth=(collide.width/2)-(width/2);
xlimit1=collide.x-twidth;
xlimit2=collide.x+twidth;

Then in enemy>draw actor>, just have the enemy walk between the two points.
