Functional mortar prefab that "launches" explosives.
Mortar prefab I used in this silly map: http://steamcommunity.com/sharedfiles/filedetails/?id=253839320
The player fires mortar by pressing E on it, and it causes an explosion after a delay. The mortar does not actually launch a projectile. This prefab contains all of the outputs and entities, but it is your job to make the mortar look pretty! In my map I used a model which was not my own so I could not include it in this prefab.
Basic overview on how to create multiple explosion locations: copy-paste a ton of the explosion entities and use PickRandom on logic_case to pick a random location to explode. OR parent the explosion entities to a track train and move it around erratically.
HOW TO USE: put the .vmf in the folder with all your other .vmfs. open in hammer and copy all entities, then paste into your map and it is ready to go.
