#summary List of all gear messages.

This is a list of gear messages. Gear messages are used to e.g. control hedgehogs.

|| `gmDestroy` || Request gear kill itself || _Not used._ ||
|| `gmSlot` || Weapons slot selected. || Used. ||
|| `gmWeapon` || Weapon seleced. || Used. ||
|| `gmTimer` || Timer set. || Used. ||

|| `gmPrecise` || Precise || _Not used._ ||
|| `gmRemoveFromList` || Remove from gear list || _Not used._ ||
|| `gmAddToList` || Insert in gear list || _Not used._ ||
|| `gmDelete` || Delete gear || _Not used._ ||

`gmAddToList` and `gmRemoveFromList` are intended for use by the engine when changing order of gears in the list.  It is not recommended that Lua changes these, and at present they are used together when changing a gear's Z (drawing order). For example, if Lua sets `gmRemoveFromList`, it would cause a leak of the gear, since Lua would no longer be able to restore it. Setting both together would have no effect since Lua cannot at present change Z.
