Triggers.
These would basically work where if you do a certain action within its radius it will activate.
Say you attach a sound trigger to a flash light. Any sound you make will turn on the flashlight.
There could be one for
Sound
If it hears something it activates
Sight
If it sees a player or monster it activates
Action
If you open a bag or shoot a gun it activates
Random
It randomly activates
And probably more if you can think of some. This would open the door for so many more impressive goop builds.
