Strange jumping animation for compiled player model.

[Burlow]

I've been attemptting to convert an NPC into a player model with the correct player model animations. I've had some success but a problem has arisen, these strange jumping animations occur now and again. To make it easier to reference I've recorded to a video below. (In the midst of uploading, accidentally posted this thread before uploading!, Woops *facepalm*)

If anyone competent would be able to point out where I've gone wrong, you'd be amazing to do so. Hopefully Ive given you enough information.

Any resources would be fantastic too!:D

As far as I know a lot of those are obsolete now. I just use these:

$includemodel "m_anm.mdl" (playermodels)
$includemodel "humans/male_shared.mdl" (NPCs)

You can use both, but if it's a playermodel, the second is just for some extra animations you'll probably never use -- just use the first unless you really want those.

On a side note, you should consider using the resources provided in:

%Steam%\steamapps\common\sourcesdk_content\hl2mp\modelsrc\humans_sdk\

It should help allow you to build a much cleaner QC as well as add some misc optimizations that tend to get ignored.

Great info! All the animations seem to be there. The jumping bug hasn't disappeared though. This entails the models feet to stick to the ground after jumping. After testing the model in TTT it seems to me that sprinting is causing the model is glitch out as the player walk speed in TTT possibly prevents an animation being done too quickly?(????)

Awesome awesome awesome. Thanks!

If you finished the upload on that video; care to post it? I can't picture what you mean unless your model's legs are made of gelatin.

[Burlow]

Only just seen your post now, so sorry! After much testing I disocovered that a few other models were acting the same way so I've came to the conclusion that it must be clientside or they might have been GMOD 12 player models.
