Alt + Space

Greetings, Unrealers

So recently, I’ve started using UE4 and decided to begin by setting my controls.
My game is in a first person perspective.
After assigning my crouch and jump keys (which are alt and space respectively), I’ve decided to test them out.

Crouch - Alt
Jump - Space

I went into the viewport and tested each individual key. It worked…
Until I pressed both Alt and Space at the same time.
I expected a crouch jump, but my viewport froze and malfunctioned. I couldn’t jump or crouch anymore after I pressed alt and space on my keyboard at the same time. However, after refreshing my viewport and blueprint, everything was fine again.

Are you using an animation for a crouch-jump? If so, you can do some simple blueprinting to make a function for a crouch jump, or at least the code required. Inside your player blueprint, try this.

Hopefully you can see that image, since I have been getting my images to be denied by something. Hopefully, this works.
