Because I have no idea what to name a mini-mod like this. In fact, I think this is more of a fix than a mod.
Notice how arrows stick to the ground after landing down? Well, the length they stay before vanishing is hard-coded so I can't do anything about that. But notice how javelins, pilums and other throwing spear types just disappear completely after hitting ground? For the longest time we thought this is also hard-coded, that javelins would just disappear upon hitting ground. Apparently this is not the case.
I accidentally found this after accidentally making a very long throwing spear, I noticed it is sticking out of the ground. After testing I found out that javelins also stick to the ground but for some odd reason unknown to us the developers made the root point with regards to the ground far too low, perhaps by mistake. So all this time, the javelins, pilums and others are still rendered by the game but we just can't see them because they're below ground. Unless the ground is made of jelly, this is not realistic.
So I modded the models of the javelin, pilum and plumbata (this one appeared only in BI) and moved them back away from the root point a little bit, resulting in these projectiles showing sticking to the ground:
I also modded the trail a bit further back to give them the same effect as before.
You can use this mod by downloading here: http://dl.dropbox.com/u/14762912/javelin_mod.zip
Note that this mod does NOT change gameplay whatsoever. This is only a graphical mod. The models do not overwrite existing files. The mod only overwrites one file only: descr_projectile_new.txt so you might want to back it up just in case. If you're using this mod for BI then this text file must overwrite the same file in bi/data as well. There should be no change in performance in using this mod, since the models used are the same, only repositioned and the game renders them anyway. But just in case, I also included the repositioned models of the lower models.
I say the biggest thing we can use this for is highly detailed arrows. Arrows now can be made in 3D form instead of single polygon objects like currently since new missile objects like this will still stick to the ground.
Apologies if someone else already discovered this and used it for their mod. I have no knowledge if that is the case.
