How to Make a Proximity Mine GMOD

1. Spawn a target finder on the floor with target players ticked and target range 200 (the number stated here is the distance someone can come towards the mine without getting blown up feel free to change this number and experiment to see what is best)

2. Spawn a simple explosive next to that with the settings you choose (simple explosives are just easier to use than normal explosives and do the same job the only downfall is that you get less options)

3. Wire the explosives detonate to the target finder (this is basically telling the explosive to explode if the target finder has a target, and the target finder would only have a target if someone came within 200 units of the target finder)

There is a more complicated way involving beacon sensors, comparison chips, target finders and explosives but there is no point in that because it does the same job and is easy to follow.

Done! now whenever someone comes within 200 (i don’t know what units are used in Gmod) the explosive will explode. You can also do this with thrusters, forcers or basically anything you can think of.
