"setbodyfield (name of the property) (value)" changes body properties, like temperature, mood
"setlimbfield (name of the limb) (name of the property) (value)" sets things for limbs - skin health, muscle health, infected etc.
"talk (text)" makes the player talk (yellow text above his head)
"heal" fully heals the player, does NOT remove amputations
"coagulate" fully stops bleeding on the player
explode also has parameters (like chance to destroy tiles, skin, muscles iirc)
"spawn (item name, items that have 2+ words for name (like "rifle magazine") is written without spaces and without underscores, so "rifle magazine" becomes "riflemagazine", some item names don't match with the displayed names, i.e. "antiseptic" is called "disinfectant", so to spawn antiseptic, you would need to write "spawn disinfectant" and not "spawn antiseptic") (how damaged is it, in decimal, 0.0 (or just 0) is completely broken and 1.0 (or just 1) is fully intact) (amount of items to spawn)" (or summon, i kinda forgot)
