How do I make a sentry trap, and as well as a trap that goes like this: There are 2 ways, they both have pressure plates, and the K!ller can activate one button out of two to make either the top of bottom one be deadly, and once the k!ller activates the button, they can’t press the buttons again.
If there’s anything that covers this, I wasn’t able to find them. Please help!
If you mean by a sentry trap do you mean by a box with a sentry in it and you infinitely stay there?
You could have the buttons transmit a channel when clicked to the sentries and have that channel deactivate the button as well.
By a sentry trap, the sentries stay deactivated until the button is pressed, and they eventually stop after a certain amount of time.
I’m probably being (not smart) here, but how would the same channel deactivate it as well?
make two zones, when you press a button both zones go off and the one you want goes on a little later. Make it so when you enter the zones it oofs you.
There is no doubt a delay from when you activate a channel, so that would mean you can press the button then have the same channel deactivate it. Just have the “button pressed, transmit” area and the deactivate when receiving on area the same thing.
Ah, so have the button transmit on a channel to all the sentries and to a repeater. The repeater makes a counter count down to 0, and when it hits 0 the sentries despawn again.
You can replace the repeater with a trigger loop to say a TON of memory. Other than that, yeah.
I mean yeah you could use a trigger loop 
(I’m always too lazy to make them)
Use the button make so when button pressed show sentry then use a trigger to make the delay so when the time is over they’ll disappear
