I'v spent the past 5 hours trying to figure out if it's possible to change a player stance using libcod without any luck.
Is it even possible to do? Or is it a client-side only?
setStance() possible?

Did you try to "reverse" the function? Never tested that, but could work.
Otherwise you could do exexclientcommand("gocrouch") for example.

Reading from the address (https://github.com/kungfooman/libcod...layer.cpp#L331)
Writing to the address (untested):PHP Code:void gsc_player_stance_get(int id) {
int entity = gentities + id * gentities_size;
unsigned char *stance_address = (unsigned char *)(entity + 8);
int code = *stance_address & 0x0F; // just the last 4 bits tell the state
char *stance = "";
switch (code) {
case 0: stance = "stand"; break; // also in spec
case 2: stance = "stand"; break;
case 4: stance = "duck"; break;
case 6: stance = "duck"; break;
case 8: stance = "lie"; break;
case 10: stance = "lie"; break;
default: printf("unknown stance for player id=%d, code=%d\n", id, code);
}
stackPushString(stance);
}
PHP Code:void gsc_player_stance_set(int id) {
char *stance;
if ( ! stackGetParams("s", &stance)) {
printf("scriptengine> ERROR: gsc_player_stance_set(): param \"stance\" has to be a string!\n");
stackPushUndefined();
return;
}
int entity = gentities + id * gentities_size;
unsigned char *stance_address = (unsigned char *)(entity + 8);
if ( ! strcmp(stance, "stand"))
*stance_address |= 0x00; // maybe 0x02
if ( ! strcmp(stance, "duck"))
*stance_address |= 0x04; // maybe 0x06
if ( ! strcmp(stance, "lie"))
*stance_address |= 0x08; // maybe 0x0a
stackPushUndefined();
}

Which does have some effect on the stance but seems to get overridden (Player starts prone animation for a split second before it will cancel).PHP Code:int* test = (int*)((*(int*)(gentities + id * gentities_size + 344)) + 12);
*test = *test | 0x800001; //80001 = prone I believe.

Maybe you need to add the code below after you set it.
Like the melee first bash bug.PHP Code:*(int *)(state + 216) = 11;

Still same problems.
Here is the output i get before & after setting stance_address;
Also for the "test" variable, it seems to do the weird split second animation no matter what I set it to which makes me think its not going to be helpful despite being related to player stance.PHP Code:stance_address = 0 //currently standing
stance_address = 4 //set to crouch
stance_address = 0 //reverted back to standing
stance_address = 4 //rinse and repeat

Did you actually try my version and tested the other "maybe-values"? Only 4 bits define the state, maybe the other 4 bits cause the problem, hence the xor-assignment.
You can also try to breakpoint on the "write" of that address: http://stackoverflow.com/questions/5...-access-in-gdb
So you can trace back which function resets the value. -

Hmm, just had a thought of another way to do it.
Currently meatbot makes the bot play the stand/crouch/prone animation when it shoots their gun. This can only be done via mp/playeranim.script
So maybe it could be possible to make a libcod function that sets the players current animation using gsc? Could be useful for many things other than bot stances.
Example;
Having a quick look, setting g_dumpAnims will report current animations being played so that is a start.PHP Code:if(player.isSprinting)
player setAnimation("pb_sprint");
else
player setAnimation("none"); //reset back to default/reset back to mp/playeranim.script

After doing a bit more research, I have discovered that if you hook bg_playeranimation (sub_80D82A4 on 1.0) and make it return 0, it does have some sort of effect on animations. However only if sv_cheats/devmap is enabled.

I digged some time through the animation functions and I could set a new animation, but it was instantly resetted. Maybe this helps you to look further without redoing whats already done.
libcod, for version 1.3 iirc:
https://github.com/kungfooman/libcod...bcod.cpp#L1920PHP Code:int BG_AnimationIndexForString(char *string) { ... }
BG_PlayAnim e.g. I just hooked to look what arguments it receives. Just play a bit around with it or add a hook to dump the arguments and still execute the original function.
The actual function calls for testing this animation stuff is here: https://github.com/kungfooman/libcod/blob/master/gsc.cpp#L1935
I was calling the closer functions by abusing a cvar, with this: https://github.com/kungfooman/cod2_s...ugging.gsc#L10
PHP Code:/rcon set closer "1100,first,second,third arg"
Today I would probably use call_function_raw though: http://killtube.org/showthread.php?2...-dlsym-dlclosePHP Code:// ps animIndex bodyPart is_0/time setTimer, isContinue, force
case 1100: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000118, 0x00000002, 0x00/*000567*/, 1, 0, 1)); // reload
case 1101: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000082, 0x00000003, 0x00/*000037*/, 1, /*0*/1, 1)); // strafejump
case 1102: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000083, 0x00000003, 0x00/*000037*/, 1, 0, 1)); // oO 1
case 1103: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000080, 0x00000003, 0x00/*000037*/, 1, 0, 1)); // oO 2
case 1104: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000000, 0x00000002, 0x00/*001000*/, 1, 1, 1)); // nothing
case 1105: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000085, 0x00000003, 0x00/*000600*/, 1, 1, 1)); // highjump
case 1106: return stackPushInt(BG_PlayAnim(0x08705480, 0x00000081, 0x00000003, 0x00/*000037*/, 1, 1, 1)); // highjump
case 1107: return stackPushInt(BG_PlayAnim(0x08705480, 6, 0x00000003, 0x00/*000037*/, 1, 1, 1));
That makes it a lot faster, no need to recompile libcod and restart the server everytime etc.
In php's CoDExtended, get_animation_index(name):
https://github.com/riicchhaarrd/CoDE...script.cpp#L16PHP Code:void GScr_xtnded_anim(int a1) { ... }
{"get_animation_index", GScr_xtnded_anim, 0},
