Hard times getting mouse position in 2.5D platformer

[Saw9yer]

Hello everyone,

I have hard times to get the mouse position in my 2.5D platformer.
I tried multiples ways :

• Line trace by channel
• Line plane intersection

I assume my difficultiles comes from the fact

• My player can only move on X and Z
• My camera has an target arm length of 1200
• My camera has an absolute rotation of 0; -10; 90 (i think this is my main problem)

Can you help me?

You can use Line Plane Intersection (Origin & Normal) | Unreal Engine Documentation to get mouse intersection on a given plane:

Hope it helps.
