I worked this out acting on a suggestion from Butter Fingers:
First you need to download and install Mattess's free crossbow although with a little tweaking you can probably do this with any weapon.Here's how I did it:
To make your crossbow shot an exploding projectile do the following.
Open up The Game Creators\FPS Creator\Files\gamecore\flak\modernday folder.
Copy the folder that says "law" to the flak\scifi folder and rename it "crossbow".
Open up the gamecore\guns\scifi\crossbow folder.
Make a copy of the "gunspec" file.
Open up the original gunspec file.
Right underneath the line that says "smoke = 1" insert this line:
"flak = scifi\crossbow" and close the gunspec file.
Your crossbow should now fire explosive projectiles.
Things to note:
1. Make abosolutely sure you back up anything before you change it.
2. Make sure you fire from quite a distance away from a wall, entity, etc. or you are going to take some damage.
Enjoy!
Once again I thank Butter Fingers for the idea.
