X-Axis Mirror mirrors the bones, but they appear on the same side So, my problem is this: I started building an armature for a character to do a walk cycle with Blender. Now with X-Axis Mirror ticked, the bones are mirrored but they appear on the same side of the mesh. Here's a picture of the problem:



So, I tried extruding the shoulder bone with Shift + E, and this is how it turned out. Blender automatically names these bones as _L and _R, why are they mirrored on the same side?
A more complete indication (than the comments):

Blender's convention for armature is mirroring along -X / +X axis.


-X is the right part of the character (on screen on the left when looking in front view)
+X is the left part (same principle)


To avoid complexity, it is good to rig your character using the same orientation and scale for both the armature and your character. And much preferably no rotation and no scale.
