= Scary events =


Today I (xtron) will show you! (the reader) how to make scary events that will yea…scare the player!.


== The door slam ==


=== The Door. ===


we will startoff this tutorial with the basic door slam!.


Start with adding a door.


Go to entities > Door > Choose a door that you want to slam. Change the name of it.


Now when you got the door added you need to change the open ammount.


Click on the door > Entity > Look for "OpenAmount" and change it to 1. 1 is just a recommendation you can choose anything really.


Now you're done with the door. Let's get going to the Script Area.


=== The Script Area. ===


Press on Area (8) > Script and make an area infront of the door like so:

When you're done with that you need to change it's name, pick anything just remember it.


Now we're done with the Script Area, let's get going to the actuall scripting.


=== The Script ===


First off we will be needing to add an EntityCollideCallBack to the void OnStart()


<syntaxhighlight lang="cpp">
AddEntityCollideCallback("Player", "script_slam", "func_slam", true, 1);
</syntaxhighlight>


When you're done adding that we will need to start working on the function.


First function we're gonna add is the actuall slam!.


<syntaxhighlight lang="cpp">void func_slam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("door1", true, true);
}
</syntaxhighlight>


That was the first function of a couple.


After the slam we want some sanity increase and maybe one or two sounds! (three actually).


void func_move_box1(string &in asParent, string &in asChild, int alState)


<syntaxhighlight lang="cpp">{
SetSwingDoorClosed("door1", true, true);
 
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
 
PlaySoundAtEntity("", "react_scare", "Player", 0, false);
 
PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);
 
GiveSanityDamage(5.0f, true);
}
</syntaxhighlight>


Now we got the door slam setup. The result of this one should look like this


<syntaxhighlight lang="cpp">void OnStart()
 
{
AddEntityCollideCallback("Player", "script_slam", "func_slam", true, 1);
} 
 
void func_slam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("door2", true, true);
 
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false); 
 
PlaySoundAtEntity("", "react_scare", "Player", 0, false);  PlaySoundAtEntity("", "close_door.snt", "Player", 0, false); 
 
GiveSanityDamage(5.0f, true);
}
</syntaxhighlight>


== The exploding door ==


The exploding door! My favorite!.


It's almost like the slaming door but with a few modifications.


=== The Door ===


You will need to go to the level editor:


Click on the door > Entity > Change OpenAmount to 0. So it's closed.


=== The Script ===


We will be using the same function as the door slam so copy&paste it.


<syntaxhighlight lang="cpp">void func_slam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("door2", true, true);
 
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
 
PlaySoundAtEntity("", "react_scare", "Player", 0, false);
 
PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);
 
GiveSanityDamage(5.0f, true);
}
</syntaxhighlight>


What you now want to do is replace the SetSwingDoorClose with


<syntaxhighlight lang="c++">
SetPropHealth("door1", 0.0f);
</syntaxhighlight>


So it looks like this


<syntaxhighlight lang="cpp">void func_slam(string &in asParent, string &in asChild, int alState)
{
SetPropHealth("door1", 0.0f);
 
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
 
PlaySoundAtEntity("", "react_scare", "Player", 0, false);
 
 
 
PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);
 
 
GiveSanityDamage(5.0f, true);
}
</syntaxhighlight>


Then we need to change the void OnStart abit.


Replace


<syntaxhighlight lang="c++">
SetEntityPlayerInteractCallback("door1", "func_slam", true);
</syntaxhighlight>


And replace


<syntaxhighlight lang="cpp">void func_slam(string &in asParent, string &in asChild, int alState)
</syntaxhighlight>


with


<syntaxhighlight lang="cpp">void func_slam(string &in asEntity)
</syntaxhighlight>


Now we're done with the Exploding door!. The result should look something like this:


<syntaxhighlight lang="cpp">void OnStart()
 
 
{
SetEntityPlayerInteractCallback("door1", "func_slam", true);
}
 
 
void func_slam(string &in asParent, string &in asChild, int alState)
{
SetPropHealth("door1", 0.0f);
 
 
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
 
 
PlaySoundAtEntity("", "react_scare", "Player", 0, false);
 
 
PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);
 
 
GiveSanityDamage(5.0f, true);
}
</syntaxhighlight>


This is how you create some door events.


I hope you find this usefull. If you got any questions or requests on tutorials please send me a PM on the forum.
