The exact code I am using is:
addEventHandler("onPedWasted", (event,ped) => {
if (ped.name == localClient.name){
spawnPlayer([486.630, 491.788, 10.547], 6, 3);
}
});

I have tested the spawn parameters on the server side and it works well. The event also isn't the issue. The error from the client side console is:

ReferenceError: spawnPlayer is not defined

... which I know to mean it can't access the function. I feel that I'm missing something really simple here. Is there another object that I need to call that function from? I already tried gta.spawnPlayer (the Wiki shows sone functions and objects needing a "gta." prefix and not others). Any help is appreciated!
