Exploading barrel

[teddan50]

Hello,

I am currently trying to make a script where a barrel suddenly will explode and turn into pieces.

This is my script:

void OnEnter()
{
AddEntityCollideCallback("Player", "ScriptArea_1", "Barrelscare", true, 1);
}
void Barrelscare(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("barrel01_pieces_1" , true);
SetPropFade("barrel01_1", "", 0);
PlayGuiSound("break_wood_metal1", 1);


}



...and also, how do I set up messages on doors? I have managed to get a message on a locked leveldoor, but I want to show a different message when a key has been used. I also want to do the same with swingdoors.

Another problem I am also having is that I have created a "scare area" and it works fine, but when I go to a different map and go back again to the first map the "scare area" is still there. How do I make it disappear?

Hope that you guys know what to do!
