[SCRIPT] Backpain

[White Dragon]

Here the code to implement the backpains:

-takedamagescript event-
call this script funcs with: takedamagescript data/scripts/ontakedamage.c

ontakedamage.c:

void main() {
  	void self = getlocalvar("self");
  	void attacker = getlocalvar("attacker");

	setoppx_ondmg(self,attacker); // backpains
}

int setoppx_ondmg(void player, void attacker) {
    setentityvar(player, 6, getentityproperty(attacker, "x") );
}

Support Functions (in script event):
Add these funcs in main script of your chara:
call these funcs with: script data/scripts/backpain.c

backpain.c

void main() {
    check_backpain(self,0);
    setprevdir(self); // for backpains
    settimebp(self); // for backpains
}

    void opp = getentityproperty(player, "opponent");
    int anim_id = getentityproperty(player, "animationid");

            // Se il nemico è davanti a noi (più a destra) ma noi siamo girati a sinistra allora backpain!!
            // Quindi valutiamo se stanno l'uno alle spalle dell'altro...
            if ( gettimebp(player) >= 0 && gettimebp(player) <= 1 ) {
                if ( (getprevdir(player) == 0 && getoppx(player) > getentityproperty(player, "x")+threshold)

[NED]

Nice!!
I like the fact possibility to have different reactions depending on position of enemy or attacker...
-Basically this is what I'll need for my "contextual" on-the-ground grapple moves.
-I'll certainly use it for back grabbing system too (if it work)
