need help with tracking mouse hover

[unique kantilope]

ok, so im still very new to lua and modding in general. and despite my best efforts i cannot find an example in other mods to blatantly steal from.

 

i want the character im working on to be able to ignite things at a distance. on key-press it would try to ignite whatever the mouse is hovering over. i've stolen most of what is needed from the games files for the fire staff. but i need a way to track what(ifanything) the mouse is hovering over.

TheInput:GetWorldEntityUnderMouse()

 

The line above returns whatever prefab the player would click on if they were to click. (this also includes prefabs without valid actions, but not prefabs without hitbox or the "noclick" tag)
