multicompare help needed

Anyone got experience of multicompare? I'm working on a puzzle that involves 2 people having to activate separate switches at the same time.

I'm using 2 buttons feeding a multicompare with the multicompare driving the door. Trouble is that the bloody door keeps opening on one switch.

Should you use overides on the multicompare's inputs, and then trigger a compare, because that isn't working for me.

The description in the help doesn't and I can't find any examples on the net.

Any data or URLs for examples would be welcome.

Thanks,

CJ

I'm not 100% sure, but isn't multicompare a hl1 entity in the mod. Try using a logic_compare.

I don't think the multicompare will work in your case... I've never gotten it working properly.

What I would recommend is using a math_counter. Here's what you do:

Set the math_counter's name to "door_counter" (or something similar), with the start value as 0 and the max as 2. Set it's output to open your door.

Now, take one of your buttons and add two outputs. The first output should be "OnIn, door_counter, Add, 1, 0.00", the second should be "OnOut, door_counter, Subtract, 1, 0.00"

Do the same for the other button.

What happens is that when one button is pressed in, it will add 1 to the counter. When the button pops out, it will subtract 1 from the counter. So only if both buttons are down will the counter add up to 2 and open the door.

EDIT: Oh, but one thing I forgot to note is that for the above example, you need to make sure the button has an auto-reset. IE it's not toggling.

I wanted to say math_counter but I wasn't sure how to use it in that way.

Hehe, yea. Math_counter is easily one of the most flexible entities around. For examples, trigger an action after all enemies in a particular wave have been killed, detect when a player enters the correct combination in a keypad, use multiple buttons to make something go, or triggering an event after a certain number of enemies in a wave have been killed. It's pretty awesome. Coupled with a few logic_branches, you can do some pretty neat stuff!

Works a treat thanks. I've actually left one switch toggling at the moment, as it lets me test on my own.

Thanks,
