First off, this is possible. You can change the projectile model in the weapon file for the knife. As for sticking where shot and such, this is much like the crossbow. You're going to have to do a fair amount of scripting. Here's an excerpt from the crossbow gsc:
Code Snippet
Plaintext
self.bolt_stuck = false; //init for (;;) { self waittill("projectile_impact", weapon, point, radius); switch(weapon) { case "crossbow_exp": wait 0.1; //give the sticky func a chance to set the var before checking it if(self.bolt_stuck != true) { time = 2.1; bolt = spawn("script_model", point); bolt.angles = self getplayerangles(); bolt setModel("t5_weapon_crossbow_bolt_world_exp1"); bolt thread crossbow_sound(time); bolt thread crossbow_fx(bolt, time); wait time; thread crossbow_explosion_sound(bolt); PlayFXonTag(level._effect["crossbow_explode"], bolt, "tag_fx"); earthquake(0.4, 1, bolt.origin, 400); bolt radiusDamage( bolt.origin, int(level.zombie_health * 0.8), int(level.zombie_health * 1.5), 350, self, "MOD_GRENADE"); bolt hide(); bolt notify("death"); } break; } }
We can fairly easily modify this for purposes of the ballistic knife:
Code Snippet
Plaintext
for (;;) { self waittill("projectile_impact", weapon, point, radius); switch(weapon) { case "ballistic_knife": wait 0.1; knife = spawn("script_model", point); knife.angles = self getplayerangles(); knife setModel( **knife model name here** ); trig = spawn("trigger_radius", point, 0, 40, 40); trig waittill("trigger", player); current_ammo = getWeaponAmmoStock("ballistic_knife"); max_ammo = 5 // (for the sake of argument, the max ammo is 5) if(current_ammo < max_ammo){ ammo_to_add = current_ammo + 1; player setWeaponAmmoStock("ballistic_knife", ammo_to_add); knife hide(); knife delete(); }else{ // keep the pickup available for another time } break; } }
You can just thread that somewhere and it should be okay.
As for the Bowie knife showing up when you acquire it, that's simply a matter of detecting if you have the knife and changing the model, which could just be a whole other weapon. Like so:
