You can make the landmine hostile to players, enemies, obstacles and NPCs then give the mine ATTACK animation in which the mine will explode when those entities are close or within range.

If that isn't good enough, I could share script to do the detecting stuff :cool:.

Thank you as always bloodbane, I'll run some tests to see if that works for now

I added an attack animation and seems to not ever do it, I am doing something wrong?

Have you declared hostile player enemy npc obstacle at landmine's header text?

If that doesn't work, you could use scripted method instead which doesn't need ATTACK animation. Well, you still need animation for the triggered state though, which is FOLLOW1 in my example below.
Here's my landmine text:
Code: 
name        mine
gfxshadow    1
type        trap
hostile        player enemy

anim    idle
@script
  if(frame>=1){
    attack4(-30, 30, -10, 10, 10, "ANI_FOLLOW1");
  }
@end_script

This is attack4 function:
C: 
void attack4(int RxMin, int RxMax, int RyMin, int RyMax, int Rz, void Ani)
{// Attack interruption with 3D range check
    void self = getlocalvar("self");
    void target = findtarget(self); //Get nearest player
    float x = getentityproperty(self, "x");
    float z = getentityproperty(self, "z");
    float y = getentityproperty(self, "a");
    int dir = getentityproperty(self, "direction");

    if(target!=NULL()){
      float Tx = getentityproperty(target, "x");
      float Tz = getentityproperty(target, "z");
      float Ty = getentityproperty(target, "a");
      float Disx = Tx - x;
      float Disz = Tz - z;
      float Disy = Ty - y;

      if(Disz < 0){
        Disz = -Disz;
      }

      if(Disx >= RxMin && Disx <= RxMax && Disy >= RyMin && Disy <= RyMax && Disz <= Rz && dir == 1) // Target within range on right facing?
      {
        performattack(self, openborconstant(Ani)); //Change the animation
      } else if(Disx >= -RxMax && Disx <= -RxMin && Disy >= RyMin && Disy <= RyMax && Disz <= Rz && dir == 0) // Target within range on left facing?
      {
        performattack(self, openborconstant(Ani)); //Change the animation
      }
    }
}

XPlosX is just an explosion entity.
