Windows Need help with dnd

[Luke B]

I am fairly new to gamemaker studio 2 and started my first platformer recently. I just added enemies into the game. I have made them move to the right (walk_spd). However, I need help getting them to move to the left (-walk_spd) when they hit a wall. Can anyone help? Remember, I'm using drag and drop.

Go to the Event Selector and select the Collision event with the wall. Then use the Assign Variable action to set walk_spd to -walk_spd.

I set the name as "hsp" and the value as "-walk_spd". It still stops at the solid. Am I doing it wrong?

What makes them stop? Make sure there's nothing else that's overwriting the code that's supposed to cause the instance to turn around.

What are you using to control movement, hsp or walk_spd? Set whichever one finally causes your instance to move.

If you control horizontal speed with hsp, then you should be setting to -hsp.

I've tried walk_spd and hsp. Neither work. Not quite sure what to do now.

Where are you applying movement to the instance? Which variable controls how quickly your instance moves?
