R2NS-ClientKillCallback

AddClientCallback_OnPlayerKilled ( void functionref ( ObituaryCallbackParams {entity victim, entity attacker, int damageSourceId, int scriptDamageType} ) customCallback)

With the new update made by Uniboi, the arguments of current callbacks need to be replaced with an ObituaryCallbackParams struct.
The struct currently contains:

• entity attacker
• entity victim
• int damageSourceId
• int scriptDamageType
• bool victimIsOwnedTitan

Example:

void function afterClientInit(){
    AddCallback_OnPlayerKilled ( myCallbackFunction )
}

void function myCallbackFunction ( ObituaryCallbackParams inputParams ) {
    if(inputParams.attacker == GetLocalClientPlayer() && DamageSourceIDToString(inputParams.damageSourceId) == "mp_weapon_sniper")
        thread myOnKillFunction()
}

Note: this is triggered each time a player gets killed in a match, not just by the client player. If you only care about client player's kills, simply check if inputParams.attacker == GetLocalClientPlayer()
