I might add another command so players can clear their own mines. The current command clears all mines.
As in, command to clear out the oldest mine?
And command? As in type?
That feels low quality...
Or how about, your AP mines come with a joystick
Click to plant, right click to fire, and L to clear out the oldest mine
You can carry 4 at a time, and upon touching another AP mine item, or obtaining it, they merge into one item, with 4/4 mines.
Throwing out the joystick and your current mines blows up all the ones out.
But that may be too complex, though, so I think the blowing up the oldest one is the best... Its all up to you though.
