Creating multiple buttons for one door

Introduction

This tutorial will detail the basics of getting a door to open only when two (or more) buttons are activated.

Door, Buttons, and Triggers

Create your doorway and two buttons by following the tutorial for creating a button and linked door through step 5 of the section titled "Triggers".

Note:Your buttons and triggers should be distinct from one another. Check all of the following on each button to make sure you have changed the button_* prefix to button#_*, with # representing which button it is:

• The name of the movement door under the button (originally button_top_door)
• The parent of your button_top_model (same as above)
• The name of the two triggers button_trigger_player and button_trigger_box

Next, complete steps 7 and 8 under Triggers on the other tutorial for each button, making sure that you are using the appropriate button#_* prefix.

Setting the Buttons to Open the Door

Create a math_counter entity, and put it near your door. Set the following properties:

Property Name	Value
Name	buttoncounter
Minimum Legal Value	-1
Maximum Legal Value	2

Now go to the Outputs tab and set the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnHitMax	door_left	Open	<none>	0.00	No
	OnHitMax	door_right	Open	<none>	0.00	No
	OnHitMax	buttoncounter	SetHitMin	1	0.00	No
	OnHitMin	door_left	Close	<none>	0.00	No
	OnHitMin	door_right	Close	<none>	0.00	No
	OnHitMin	buttoncounter	SetHitMin	-1	0.00	No
