|fixture||the index of the fixture|
|friction||the friction of the fixture must be between 0 and 1|
Friction is the force that resists the relative motion of
material elements sliding against each other, which in the
GameMaker: Studio physics world, translates as the loss of
momentum caused by the collision of two instances with fixtures
bound to them. So, when two instances collide, their motion is
affected by this value, with a high friction causing a larger loss
of momentum than a lower value.
The code above will set the friction of the fixture indexed in "fix_brick" to 0.1.
