BP to turn on/off a television

Development Programming & Scripting Blueprint
,

Hey, you guys. I´m studying Unreal 4. I have a little doubt. I want to put a television on my scene. However, I want find a way to turn on/off my television using a button on my keybord. I find a way to do the same in a lamp, but I could not find a way to do this on my television. Did you guys have any blueprint which would let me do that with a television?

Thanks in advance

Yes, the answer depends on your problem.

  1. Is it the actual input - the pressing of the key? How to get that to affect the television? Then, put an input event in your character or player controller for the key you want. Off of this input event, get all actors of class (television) and then, for each one, turn it off or on.

  2. Is it the turning on or off of the television? Do you want to figure out how to give it the effect of being “on” or “off”? Then, create two materials: one for On (image or color) and one for Off (black). When it turns on, set the material of your mesh to the On material, then set it to Off when it turns off. You could also include a point light and set the intensity when it turns on or off.

NOTE: To optimize #1, you could get all televisions on begin play, then save that as a variable which you loop through when the player presses the input.

Hello, Nacho! I make a little advance in my BluePrint. And my current problem now is that I cannot turn my screen to black. When I turn my tv to off, my screen just freezes the image and that´s all. Thanks in advance.

Hey you guys. I uploaded a screen from my nodes. Like I said. The television turns on when the character get close and everything, the problem is when I try to turn it off. The screen just freezes and don´t turn back to the black screen.
