As no one seems to know the answers, I've decided to ask them here:

"TEX_COLOR" - I used view entities for weapons, and I used to change they color depending on the textures color under players feet.
I was simply tracing under player's feet with SCAN_TEXTURE and then setting entitie's "blue" to "tex_color", but now it doesn't work.
I tried "tex_light" as some one recommended me, but that doesn't work as well, plus "tex_color" works under C-SCRIPT but not with LITE-C.

"PH_CONVEX" - this doesn't work for me... It's different to "PH_POLY" (which has proper hull), convex works like this for me:

I would like to know, what am I probably doing wrong? Model is simply, and it's count isn't more than 256 p.

"PH_HINGE" - I've started learning constants, and it's seems pretty simple, but I found out that I can't understand something...
I've set no limit's for joint, and I rotate it in it's TILT, plus I apply velocity, so it should turn clock wise, and it works.
But it turns only about 2 times, and then stops.. Didn't I set full limit at hinge? Or what am I doing wrong? Thanks.

For detecting texture colors under the player, look for "c_trace" and "hit" in the manual. TEX_COLOR can not be used for that.

The collision behavior you're getting with PH_CONVEX could be caused by a too-big hull of the other entity, or a skin width setting too large for the scale of your objects. At least that's the 2 things I'd suspect at first.

As to the hinge problem, does it stop suddenly after 2 turns, or does the movement slowly cme to a standstill?

I'll take a look at "hit", thanks. But I would like to know, "tex_color" doesn't work with lite-c for that purpose, right?

The action is the same as for the hinge, which I try to move, but without applying velocity, it's looks like this:
As you see, skin width is "0"... Didn't get about too-big hull, could you explain?
Plus, it works perfect with all other models if I make it static with PH_POLY.
Here is the same problem with different models:


About stopping hinge, as I placed model at the level, it has -15 tilt, then when I debugged it's tilt, I see that it was decreasing till -90 and then increasing to -0.002 and at this position it stops. I was wrong about 2 turns, it makes only half way. And it stops at the same angle always, I have no idea why.

I got an answer for problem with convex, rojart says that it's like this:

Others problems still exist.

@3Run your picture reminds me of my old Physics multiplayer demo when i used green for sending and red for nonsending objects^^

What project is that? Any videos, pictures, source?

you even visited it^^

edit: oh and with Physics i dont mean physix

Thank you 4 the link, now I remembered it.

"hit" works but it doesn't detect dynamic lights, but "tex_color" used to detect them in C-SCRIPT. How do I get it to work with LITE-C?

And what about HINGE why does it stop? Or is there anything wrong in my script? Thank you in advices.

To detect dynamic lights, there are several functions - look for ent_nextlight or view_to_light. TEX_COLOR was an old A6 variable for storing the shadowmap, and was long ago replaced by CONTACT. It had nothing to do with detecting dynamic lights.

As to the stopping of the hinge, does this only happen with the tilt, or also with the pan angle?
