Hello everyone,
I have made a Blueprint to move a mesh to the position of the cursor of the mouse, you will find it below.
This works well when I try to move the mesh but when I click on my mesh, it “flies”. It is going upper in the Z axis.
Someone now how I can lock the Z axis, in order to have my mesh staying at z = 0, please ?
Thank you !
After you set your “mouse location” from the hit result you can set the Z of “mouse location” to the Z of “Original Location”. This should keep your character at the same Z value and avoid him flying up and down.
Is it a new node to add or on one existing node on the screenshot ? I don’t find this option … 
I can’t go into great detail as I’m at work and can’t actually see what I’m talking about. But you should be able to break the vectors to acquire their Z position. You would then set the Z position of Mouse location to the Z position of your Original Location.
I would highly recommend watching this tutorial series if you haven’t already. UE4 Blueprint Tutorials
Thank you Snackmix ! It works with break vector and make vector 
No problem! Glad you got it figured out
