rst bge touch ups: making the title of the examples slightly more noticeable - it's still not correct, comparing to the other examples, but at least it looks okish. - fixed some small typos 2012-01-23 19:53:23 +00:00			`++++++++++++++++++++++++`

BGE: Cleanup constraints documentation * Fixing Python example. Behavior has changed with Blender 2.74 * Adding missing return type * Fixing typo simbolic * Fixing note for upper/lower limit * Adding link to constraints constants 2015-05-10 15:58:17 +02:00			`# use bottom right edge of Object1 for hinge position`
