Move back and forth

Jamwithno

i want the enemy to go back and forth. right now i have it so that when the enemy touches and enemy wall it goes the opposite direction but its not working. Do you guys know of any other ways of doing this?

Hi Jamwithno, a couple or more ways to do this; here's a straightforward way:

Make a game text attribute called Direction, set its value to right.

Place your Actor enemy wall for the left and right walls. Unlock both, in the left wall's Rules put:
When Actor receives event overlaps or collides with actor of type Enemy
Change Attribute game.Direction to right

and in the other wall:
When Actor receives event overlaps or collides with actor of type Enemy
Change Attribute game.Direction to left

Then in the Enemy (moving) actor's Rules:

When Attribute game.Direction is right
Move Direction 0 relative to scene, chosen speed

When Attribute game.Direction is left
Move Direction 180 relative to scene, chosen speed

Hope it helps. :-)

It did not work but i think i might be doing it wrong

I've just run a test and it's working fine here; couple of things maybe to point out: make sure the 2 wall actors on-screen are unlocked i.e made instances, and make sure that in the Enemy actor's rules, that they are two seperate Rules, not one inside the other.
