I don't know how to do videos, sorry.
But it's an API. Alone it doesn't do anything.
What it does depends on how you use it. It will find a path between two points. This can be used for example to make NPCs walk/fly around randomly without predefined waypoints or creating some kind of target seeking missile.

I will make an Info video as soon as I reach the state of fully using it in my mod.

Hey buddy, you forgot something in your example
Code:
SavePos(id, pos) {     new Float:Origin[3];     new Float:End[3];     new hTrace;     pev(id, pev_origin, Origin);         xs_vec_copy(Origin, End);     End[2] -= 1000
    hTrace = create_tr2()
    engfunc(EngFunc_TraceLine, Origin, End, IGNORE_MONSTERS, id, hTrace);     get_tr2(hTrace, TR_vecEndPos, Origin);     free_tr2(hTrace);         Origin[2] += 10;     xs_vec_copy(Origin, gPos[pos]); }

Btw, this plugin seems to be wonderful. I think someone must do a NPC moving example, you'll be the fucking boss

I didn't even know that was required. I thought EngFunc_TraceLine created it's own handle.
It seems to be working fine without that. But if is required I will of course update the API and the example with that as soon as possible (worst case, this weekend).

Code:
    //With 1.71 you can pass an optional TraceLine ptr for trace natives
    // it can be 0, for meaning "global tr handle" (for get/set_tr2), or
    // it can be any other TR handle (such as one from a TR hook)     EngFunc_TraceLine,          // void )   (const float *v1, const float *v2, int fNoMonsters, edict_t *pentToSkip, TraceResult *ptr);
When reading that I get the impression it is not required.

Yeah, you can do it freely, bad thing is that you're using free_tr2 with an empty variable, don't know if free_tr2 validates it before freeing something, but we're just coding the syntax.

Impressive, so this can be set auto way point to NPC right? can someone create a simple plugin that can make a npc move on itself? Because this is too advance for me
