[SCRIPT] Scripting simple button

[Froggit]

Fair point, but if it's something as basic as that, it means they have no idea how to script. I thought I would send them in the right direction

void OnStart()
{
AddEntityCollideCallback("Player" , "ScriptArea_4" , "HallwayScare" , true , 1);
}

void HallwayScare(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("", "27_jam.snt", "Player", 0.5f, false);
SetEntityActive("corpse_male_1", true);
AddPropImpulse("corpse_male_1", 0, 0, 250, "world");
AddTimer("look03", 2.0f, "Timer_1");
PlaySoundAtEntity("", "24_iron_maiden.snt", "Player", 0.5f, false);
}
void Timer_1(string &in asParent, string &in asChild, int alState)
{
}
How do I know when to put the extra timer at the end when there is no callback
