unfortunately, you can’t make custom consumables like med packs and shield cans. however, you can have a game overlay that is a button called “eat food.” then wire this to a checker:
button pressed > run check
on the checker, have it check if the player has >0 of the item you want to use as food (this can be any item.)
then wire the checker to an item granter that grants -1 of the item:
check passes > grant item
then add another wire from the checker, this time to a health granter that grants whatever the amount of health you want to heal is:
check passes > grant health
and you’re done!
if this helped, remember to mark a solution!
edit: also, if you want to, add a notification, and set the notification type to “error” (find this setting in “all options”).
set the notification text to something like, “oops, you don’t have any food to eat!”
then wire the checker to the notification:
check fails > send notification
also, make sure that in the notification’s settings, “send notification to” is set to “triggering player”.
