Hi! I am trying to disable the “W” key when I enter a trigger. First, I created a bool variable in my player character. Then I added a pressed key “W” and connected it to a branch, followed by bringing in the bool variable and connecting it to the branch. I did make the bool variable set to true but…

First of all what I recommend for testing all of this is to use Print Strings so you can see exactly when it’s being called. To disable a key there isn’t a node that literally “turns it off.” What you’re really doing is disabling the logic that runs behind that input. You could do this with branche…

logically if you’re trying to disable it, it should be false. You could rename it from DontMove to CanMove. (not important but does make sense) Off W dont set the bool, you’ve already done that in your trigger box, just run your logic (ie ApplyMove) off true (assuming its CanMove)

Am I doing it correct when I am using the Cast To in my level blueprints? Also, should I be doing this in my Character blueprint or should this be done in my Controller blueprint? I am bit confused by what you mean when you say “just run your logic”. Sorry for all the questions, I have been stuck o…

If anyone knows the easiest way to set this up using the First Person Blueprint with 5.6, that would be extremely helpful. Any images would also be helpful. Thank you!

Hi @bigboy2k , Do you want to disable the player’s forward movement when they enter the trigger, or do you have another function bound to the W key?

[image] bigboy2k: I am bit confused by what you mean when you say “just run your logic”. well by disabling W i assume you mean disable the logic that comes after W. So lets assume that is MoveForward. if you put MoveForward on the true path and Set CanMove to false then it wont fire.

I actually just want to know how to disable any key when entering a trigger but I am using “W” as an example because I do want to stop the player’s forward movement. I have looked everywhere and I haven’t been able to find one solid example of how to do this or any video regarding how to disable a …

Thanks for the response. I understand what you are saying but I don’t know what that would look like in Blueprint. Do you have a way of showing me what that looks like? Thanks!

Create a folder called Interfaces in your Content/FirstPerson/Blueprints directory. [image] In the Interfaces folder create a BP Interface class. Name it BPI_Pawn. [image] [image] Open the class and create a new Function called BlockMovement. [image] Open your character class, go to Class …

@BRGEzedeRocco @Rev0verDrive Thank you so much for your detailed responses. This will not only help me but the others out there that may also want to implement this. Thank you, thank you, thank you! :grinning_face:

If (can Move) don’t process ‘W’ input, else allow movement
