Hi Everyone 
I loaded one simple UI on the a cube mesh via script canvas and I have questions , how to click on the button or slider , cause does not work, looks like my ui is disable! but I’m sure did all steps till now, and this point on, I do not know how to interact with the mouse pointer with the scrtipt canvas, How to interaction on Click button or Enter text in a UI 3D Mesh with Script Canvas?
I Solved myself without mouse(Screen Center Point) 
Is it possible with Click Mouse via Script Canvas?

the Sample not user friendly without mouse! (With center point trick and color highlight cover on elements like buton, slider , etc)

When My Pointer is on the slider , and I click on the slider , button event actived & Pressed(I selected Press button is red color)! you can see mouse curosr is not active , only here is a pointer in screen center by a UI File loaded.

I solved myselft, this is related to Player Camera + Screen Center Pointer + Physics Legacy + Mesh Type (without mouse course AND The question for the new physics library is whether this can be implemented?)

I Solved Interaction UI & 3D Mesh with Script Canvas with Mouse cursor & Clicks on slider & button & textarea ,etc
