Is there a way to get a whole bunch of planes to mirror themselves along a single axis in game using logic bricks? I have my planes parented to the bones of my armature to make a 2D character and I want him to be facing left when I push and right when pushing because it is a 2D game. Right now I have two copies of my character. One facing right and one left and I have it set up so that all the planes turn invisible when the opposite button is pushed which makes for a lot of logic bricks. Does that make sense? If they just mirrored along their net origin point on the z-axis in my case, that would be way easier. I will post a pic of my current situation when I get home if you need it.

You can scale the object with negative value along a single axis to get a mirror.

To do so, play an action with scale keyframes:

  • frame 1: scale = (1,1,1)
  • frame 2: scale = (-1,1,1) [depends on your mirror axis]

Hint: As this is no turning, you still will see the front side when flipping. This means you can keep Backface Culling enabled.

  • $\begingroup$ Brilliant. How do you do scale keyframes? Do you just push s, or is there a box where you add in the values? Will this work while the armature is in the middle of another action? $\endgroup$

  • $\begingroup$ Press <s> enter -1 and a key indicating the axis to scale along e.g. <x>. Do not forget to create a keyframe with <i>. $\endgroup$

  • $\begingroup$ Say you are pushing right to go right then you stop then you go right again without turning left. How do you keep the turning-around action from playing then? I only need it when I change directions, but not every time I push the button. Other than that, I'm excited that this method works so much better. :D $\endgroup$

  • $\begingroup$ You detect (or remember) what direction the object is currently facing. Then you can decide if you need to turn or not. $\endgroup$
