The if and if else statements

[T122002]

Hello everyone! I have a question to ask.

Most script functions I have a general idea on how to use, but I do not understand how the "if" and "if else" statements work, or how or when to use them. I think after I learn those two statements, than I'll start working with loops and try to mess with puzzles a bit more.

Well, for example, say I want the player to pick up a key, then when they leave the room the key was in, a monster spawns. Or maybe when you do something, like solve a puzzle (I also don't know how to do puzzle scripts), then something will happen.

Can anyone explain to me how to do this, like dumb it down so I can understand and maybe throw in a few examples for me to study? That would be much appreciated!

You could see it as asking a if question.

IF the door is closed, do this. ELSE do this.
Example:

Code: (Select All)

if((ifyourdoorislocked, ifplayerhasanitem) == true or false)
{
Do some things
}
Else
{
Do other things
}

I'll give you a link to all these commands once I'm back on my pc

Hope it helps!

Edit: I see your computer already gave the link, good luck

Technically, you don't need if and else statements for that. Just have an interact callback for the key that adds a collision callback for leaving an area that then activates a monster.

Or maybe when you do something, like solve a puzzle (I also don't know how to do puzzle scripts), then something will happen.

Depending on the puzzle's complexity you also may not need if and else statements.

Hmm..well okay. At least I won't need the if and if else stuff right now then, since you answered exactly what I wanted. But, what are the script functions to pull off the interact callback and the collision callback? I can't find them at the Engine Scripts page, unless they're named differently there.
And thanks for the link for the if else thing, its very helpful!

I saw the site, but I couldn't find the functions.

Is there a specific function on how to do this? I mean, how would I set that up?

void OnStart()
{
SetEntityCallbackFunc("KeyName", "AreaActive");
}

void AreaActive(string &in asEntity, string &in type)
{
SetEntityActive("NameOfArea", true);
AddEntityCollideCallback("Player", "NameOfArea", "MonsterTrigger", true, 1);
}

void MonsterTrigger(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("MonsterName", true);
}

Ooh! Thank you so much for the functions! This was exactly what I was looking for!
