Some ideas I had about landmines (might make a github branch for them):
- Currently landmines detonate instantly. Instead, they should only detonate when you step off them, alerting the player when they've stepped on a mine but not detonating it (yet) - this is a movie trope that doesn't work IRL, but I think it's a neat thing to have.
- To tie in with the above, you should be able to drop items on the same tile as the mine to weigh it down in an effort to stop it from going off. This adds gameplay value because you might have to sacrifice a bunch of items in order to keep the mine from going off, and you're not going to get them back without detonating the mine.
- To preserve the original functionality of the mines, they should now be proximity mines or trip mines - I like the idea of trip mines better because it's low tech, whereas proximity mines imply a level of technology not present in IVAN.
- Possibly add directional mines - these detonate if you enter the tile that they are facing, and launch projectiles in that direction a la wand of striking. Could be disarmed by simply picking them up since they don't detonate in the same tile. Would require significantly more effort to implement than the others in this list, probably.
- Bouncing betty-type mine. Detonates when you enter any tile next to it, but unlike the directional mines it fires off in all directions (could just use generic explosion like the current landmines)
Only issue is that I think the bouncing betty mines are going to be pretty frustrating since you won't be able to detect them since you currently need to be within 1 tile of a trap in order to detect it via searching.
Same applies to the directional mines if you step into their firing line, you won't know it was there until it's already gone off - but that's how landmines work currently anyway.
Directional mines would still be set off by levitating players, trip mines would not.
To fit in with the low-tech thing I mentioned earlier, directional mines would instead have a series of wires projecting from them rather than some means of being able to magically detect passersby.
