Yes, you can do that. As you said you don't want someone to just give you the script, tell me what you need help with.

AddEntityCollideCallback.

Well, not exactly. What are you trying to spawn? I'll give you the script since I think you need to know how it's set up first.

Be carefull when trying to spawn things like cabnits, not every enitity can be spawned in like that.

What you need to do is put the lantern where you want it to spawn in the level editor, untick "active"

Now go into the script file and put this

void OnStart()
{
AddEntityCollideCallback("Player", "Script_Area_1", "SpawnLantern", true, 1);
}

void SpawnLantern(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("Lantern", true);
SetEntityActive("Cabnit", true);
}

Yes, it is possible. But as I said some things wont spawn in like that (every item will though) but tables and stuff like that wont.

You can spawn in enemies,items,other script areas stuff like that with that script c:

Pretty much, but then you would have to use forces to push the guy.
