TriggerTriggerer - Saving Object Trigger Amount
by AkyV

Perhaps it is well-known for some of you, because it seems an old TRLE trick, but I must admit it is a brand new revelation for me, so I'll share it with you - because probably some of you also aren't aware of it:

So the question is how we can save object/trigger amount if we want to enable a trigger, using a Trigger Triggerer object on it.

This "trick" works with Key, Switch and Pickup setups:

KEY
Original setup:
Square#1 - contains:
- a key hole
- a KEY trigger for this hole
- a TRIGGER trigger to activate a Trigger Triggerer object
Square#2 - contains:
- that Trigger Triggerer object with its blue frame
- the trigger that is disabled till that Trigger Triggerer has been activated

It is 2 objects+3 triggers

Alternative setup:
Square#1 - contains:
- a key hole
Square#2 - contains:
- a KEY trigger for that hole
- a TRIGGER trigger that is disabled till the key has been used in that hole

It is 1 object+2 triggers

So you saved 1 object and 1 trigger amount.

The "alternative setup" is the well-known Key setup, except the hole and the triggers are over different squares.
So Lara cannot activate that trigger on Square#2. If she uses the key on Square#1 then nothing will happen - but, after that, she will be able to activate that trigger on Square#2.

And, just think about it:
The benefit is really big if the disabled trigger has many squares - for example six squares:

Original setup:
Square#1 - contains:
- a key hole
- a KEY trigger for this hole
- six TRIGGER triggers to activate six Trigger Triggerer objects
Square#2, 3, 4, 5, 6, 7 - contains:
- those Trigger Triggerer objects with their blue frames
- the trigger that is disabled till that Trigger Triggerer has been activated

It is 7 objects+8 triggers

Alternative setup:
Square#1 - contains:
- a key hole
Square#2, 3, 4, 5, 6, 7 - contains:
- a (six squares sized) KEY trigger for that hole
- a (six squares sized) TRIGGER trigger that is disabled till the key has been used in that hole

It is still 1 object+2 triggers!

SWITCH
Original setup:
Square#1 - contains:
- a switch
- a SWITCH trigger for this switch
- a TRIGGER trigger to activate a Trigger Triggerer object
Square#2 - contains:
- that Trigger Triggerer object with its blue frame
- the trigger that is disabled till that Trigger Triggerer has been activated

It is 2 objects+3 triggers

Alternative setup:
Square#1 - contains:
- a switch
Square#2 - contains:
- a SWITCH trigger for that switch
- a TRIGGER trigger that is disabled till that switch has been used

It is 1 object+2 triggers

PICKUP
Original setup:
Square#1 - contains:
- a pickable item with OCB=64
- a PICKUP trigger for this item
- a TRIGGER trigger to activate a Trigger Triggerer object
Square#2 - contains:
- that Trigger Triggerer object with its blue frame
- the trigger that is disabled till that Trigger Triggerer has been activated

It is 2 objects+3 triggers

Alternative setup:
Square#1 - contains:
- a pickable item with OCB=64
Square#2 - contains:
- a PICKUP trigger for that item
- a TRIGGER trigger that is disabled till that item has been picked up

It is 1 object+2 triggers
