How do you make an object move in 3 directions?

[DnALANGE]

Easyest way imo could be;
Create 2 entyties and copy them in your mod.
Change the names for example to;
Your_Entitie_1
Your_Entitie_2

Open the modeleditor and go for the User Defined Variables and change the values there.
The "MoveAxis" and the "open ammount" are the ones you should check.
Good luck, testing and testing it.
That is how making games\mods work.
