Line trace only fires when both Pressed and Released (of LMB event) is connected to LineTraceForObjects

I did this is one of my projects; Give me a moment to dig around and see what I did.

Hm… Odd… Perhaps you need a branch on the hit or something. Or maybe put the Left Mouse Button in an InputAction or something - Take a look at my script and see if it helps you in someway: gZv1lLyt posted by anonymous | blueprintUE | PasteBin For Unreal Engine 4

My line trace only fires when both the PRESSED and RELEASED function of the Left Mouse Button input event is connected to the LineTraceForObjects input.

Why doesn’t it fire when only PRESSED in connected? Should there be an alternative event for released? And if so, what should it be?

Here’s is the screenshot of my current blueprint:

Hi thanks for the help.

But it seems that now it’s suddenly firing. Pretty sure I didn’t change anything so have no idea why it works now.

Now I’m wondering if you could maybe help me with another problem (posted it as another question)?:
