I need help with creating more than 1 scripts for my custom story

[ironman0001]

No, all your scripts start from there. You should never have more than one OnStart, OnLeave, or OnEnter.

Well i played one custom story and it has alot of scripts and i only see void OnStart. Here is the script: void OnStart()
{
AddUseItemCallback("", "key_1", "level_wood_1", "UsedKeyOnDoor", true);
AddEntityCollideCallback("Player", "ScriptArea_1", "Scary_1", true, 1);
AddEntityCollideCallback("Player", "ScriptArea_2", "Scary_2", true, 1);
AddEntityCollideCallback("Player", "ScriptArea_3", "Scary_3", true, 1);
AddEntityCollideCallback("Player", "ScriptArea_4", "Scary_4", true, 1);
