Uhh. I've hit the same snag that stopped my own actors. The point where the feet interact physically with the ground, it's too high. So the guy walks on his knees right now.

Find the Stand Path (in the walkpaths) and adjust the Y value.

When I replaced the files with the Coalation soldier happened the same, I hope that what CaveCricket says will work

It does, but it will take a while for me to finish it, because it involves completely changing the walkpaths... and I have to do that segment by segment.

So good luck, and thanks for helping

EDIT:

I'll try to code the light soldier

Hey, these look cool.

Can't wait for the release!

The rifle's ready, but you'll have to ask Sky if you want to beta.

I would like to wait until I make the light soldier and then release both as beta

Sky buddy, I'm waiting to see my weps

Don't be discouraged to use snippets of other's work, just ask, and follow the conditions.
Real nice work, and there are many things you can do, so don't have any ini, or lua file untouched.

And are there going to be more protection for these guys, I mean there are many things you can do with attachments ( explosions, gushing fire, external weakspots ... ) .

Don't bend over to your fans suggestions, and take it without a fight, but don't scare them off so much that they start eviscerating you.

Metal Meltdown is really helping me, and it's great as it is my 1st mod, so a bit of help is not bad

I don't have problems with light soldier coding, but heavy soldier if I replace it on any other sprites It looks really strange when it faces to left.

... What? [|] [||] [|||] [||||] ( These are lua snippet hotspots )

Oh, and don't go short on lua, it does wonders.

How does the heavy soldier look "wierd?" If the colors go all funky, that's because it's a palette problem. To fix, copy the palette into your folder. Copy and paste your sprite into that copied palette, and then it should be fixed.
Thanks to Shook for that tip.

They look as if they were crawling

They should look like the one in the red square.

(I replaced the sprites over Deimos Federation soldiers)

The "StandPath" offset is to low. And your Heavy looks like it has very long legs.
