Shake Function

[Carlos2295]

Hi there, I was working on a custom story and I was wondering how I would make the screen shake, sort of like when the shadow roars. I used the wiki and made this code, however, it doesn't work when run. Any suggestions would be really appreciated. Here's what I've got so far:

PHP Code: (Select All)

void OnStart()
{
    AddUseItemCallback("OpenDoor", "librarykey", "level_wood_3", "UnlockLevelDoor", true);
    AddEntityCollideCallback("Player", "PlayerCollide", "ShakeFunction", true, 1); 
}
void OnEnter()
{
    PlayMusic("02_amb_safe.ogg", true, 0.9, 1.0, 1, true);
}
void OnLeave()
{
    StopMusic(1 , 1);
}
void UnlockLevelDoor(string &in item, string &in entity)
{
    SetLevelDoorLocked(entity, false);
    AddPlayerSanity(100);
    RemoveItem("librarykey");
    CompleteQuest("", "LibraryDoorQuest");
}
void memento(string &in asEntity)
{
    AddQuest("", "LibraryDoorQuest");
}
void ShakeFunction()
{
    StartScreenShake(1,2,1,4);
}
