Spell System
I've had this for a while, and I've finally wanted to release it for those newer RPG servers looking for a spell system. I'm not sure how much more efficient this is over other means of doing it, but it's a start and is documented for easily changing it.
In a weapon given to everyone called "-System/Spells" or similar (which will require that you change all "-System/Spells" to whatever you name it):
PHP Code:
function onActionServerside(cmd,p1) {
if (cmd == "TakeMana")
mana.flag.here -= p1; //input wherever you store the mana flag at 'mana.flag.here'
}
//#CLIENTSIDE
public function fireSpell(stats) { //fired from the spell weapon
temp.spellName = stats[0];
temp.action = stats[1];
temp.cast = stats[2];
temp.ani = stats[3]; //projectile
temp.mana = stats[4];
temp.freeze = stats[5];
temp.power = stats[6];
temp.cooldown = stats[7];
if (mana > mana.flag.here) { //input wherever you store the mana flag at 'mana.flag.here'
player.chat = "You don't have enough mana to cast " @spellName@ "."; //if you have a message system you can use that instead
return;
}
if (this.("cooldown_" @spellName) != null) {
player.chat = spellName@ " is still cooling down for " @this.("cooldown_" @spellName)@ " seconds."; //if you have a message system you can use that instead
return;
}
if (action == "hurt") { //a spell that hurts a player
if (cast == "projectile") { //a hurt spell that is a projectile
freezePlayer(freeze);
setAni("grab",null); //placeholder
sleep(freeze);
setShootParams("spell","hurt",power);
temp.angle = getAngle(vecx(player.dir),vecy(player.dir)); //shoots in a straight line
shoot(player.x+vecx(player.dir),player.y+vecy(player.dir),player.z,angle,1,0,ani,null);
}
}
if (action == "heal") { //a spell that heals a player
if (cast == "projectile") { //a heal spell that is a projectile
freezePlayer(freeze);
setAni("grab",null); //placeholder
sleep(freeze);
setShootParams("spell","heal",power);
temp.angle = getAngle(vecx(player.dir),vecy(player.dir)); //shoots in a straight line
shoot(player.x+vecx(player.dir),player.y+vecy(player.dir),player.z,angle,1,0,ani,null);
}
if (cast == "self") { //a heal spell that is cast on yourself
freezePlayer(freeze);
setAni("grab",null); //placeholder
sleep(freeze);
//go to health system and heal using the amount 'random(int(power[0],power[1]))'
}
}
triggerServer("gui","-System/Spells","TakeMana",mana);
makeVar("this.cooldown_" @spellname) = cooldown;
scheduleEvent(0.05,"Cooldown",spellName);
}
function onCooldown(spellName) {
if (this.("cooldown_" @spellName) > 0) {
makeVar("this.cooldown_" @spellName) -= 0.05;
scheduleEvent(0.05,"Cooldown",spellName);
}
}
function onActionProjectile(spell,action,power) { //when being hit by a projectile
if (spell == "spell") { //make sure it's a spell and not some other projectile
if (action == "hurt")
//go to health system and damage using the amount 'random(int(power[0],power[1]))'
if (action == "heal")
//go to health system and heal using the amount 'random(int(power[0],power[1]))'
}
}
In spell weapons that are added from being bought/learned (I'm using "Barrel" as an example; these have to be able to be fired [D] or create your own way for firing them):
PHP Code:
//#CLIENTSIDE
function onWeaponFired() {
temp.stats = {
"Barrel", //name
"hurt", //action
"projectile", //cast
"woodenbarrel", //projectile animation
20, //mana
2, //freeze
{1,5}, //power
5, //cooldown
};
findWeapon("-System/Spells").fireSpell(stats);
}
