I'm working on various types of explosives such as proximity mines, pressure mines and even remote detonated explosives.
For proximity mines the idea is that once your within a close enough range of the mine it will trigger to detonate. If you shoot it or another explosive goes off near by, it will detonate instantly. Currently it only affects other characters if they use the following line of code:
nearactivatable=0:settarget,activatetarget=2
However most characters in FPSC do. Its basically any character that has the ability to open doors.

You can watch a video of my proximity mine tests below:

Pressure Mine Test Video
I've also made pressure mines which may come in handy for your World War 2 set games. These types of mines are activated if the player happens to step on one. But will not detonate until the player has stepped off the mine. In the video example you can see it even works on enemies.

I may poke around with the idea of remotely detonated explosives as well soon.
