-force_aimed_shots and disable_aimed_shots allow overriding the normal rules regarding which weapons are allowed to make aimed attacks. (e.g. weapons that cause explosive damage normally cannot normally make aimed shots.) force_aimed_shots will allow a weapon to make aimed shots even if it normally couldn't, and disable_aimed_shots stops a weapon from making aimed shots even if it normally could. Both of these functions affect player and npcs alike. force_aimed_shots does not override the effects of the fast shot trait. The list of edited weapons is not saved over game loads, so you need to call the functions once at each reload. Use a pid of 0 to represent unarmed.

 get/set_critter_skill_points will get/set the number of additional points a critter has in a skill, on top of whatever they have from their stats and other bonuses. Note that skill points are part of the proto, so calling set_skill_points on a critter will affect all critters that share the same proto.
