[SCRIPT] Can't progress without picking up note+key Script?

[DnALANGE]

Make 2 script area's.
You can do it on the exacpt same spot.
Then do this for the FIRST look :

void OnStart()
{
AddEntityCollideCallback("Player", "FIRSTSCRIPTAREA", "JUSTYOURSCRIPTNAME", true, 1);
AddEntityCollideCallback("Player", "SECONDSCRIPTAREA", "JUSTYOURSCRIPTNAMETWO", true, 1);
SetEntityPlayerInteractCallback("YOURKEYNAME", "JUSTHECALLBACKNAME", false);
}

+ DEactivate the second scriptarea in the leveleditor.

void JUSTHECALLBACKNAME(string &in asItem)
{
SetEntityActive("FIRSTSCRIPTAREA" , false);// FIRST script will DEACTIVATE
SetEntityActive("SECONDSCRIPTNAME" , true); //This is when the SECOND script is getting ACTIVE :
}
