Switch a light on when you enter an area? - rallelol - 01-12-2012
Hello! I was just wondering how you get a light to turn on when you enter a certain area, and if it's possible.
I'm thinking of a regular "candle_floor" or something in the lampentity tab.
Thank you!

Detect Player entering ScriptArea:
Code:
void AddEntityCollideCallback(string& asParentName, string& asChildName, string& asFunction, bool abDeleteOnCollide, int alStates);Calls a function when two entites collide.
Callback syntax: void MyFunc(string &in asParent, string &in asChild, int alState)
alState: 1 = enter, -1 = leave
asParentName - internal name of main object
asChildName - internal name of object that collides with main object (asterix (*) NOT supported!)
asFunction - function to call
abDeleteOnCollide - determines whether the callback after it was called
alStates - 1 = only enter, -1 = only leave, 0 = both
Turn lamp on:
Code:
void SetLampLit(string& asName, bool abLit, bool abEffects);asName - name of the lamp
abLit - true = on, false = off
abEffects - true = use effects, false = don't use effects when turning on/off
Example:
Code:
void OnStart()
{
AddEntityCollideCallback("Player", "LAMPAREA", "CollideLAMPAREA", true, 1); //Add the callback for the player (calls "CollideLAMPAREA" when entering)
}
void CollideLAMPAREA(string &in asParent, string &in asChild, int alState)
{
SetLampLit("MYLAMP", true, true); //Turn lamp on

SetLightVisible(string& asLightName, bool abVisible);
first but it obviously didn't work.
Thank you though!

eh...
SetLightVisible(string& asLightName, bool abVisible);
is for point lights, box lights and spot lights
SetLampLit
is for lamp entities
