Hello,
I’d like to know how to make a Matinee play when I aim the Crosshair then click on the specific mesh in the third person template, like in the GIF down below. I know this is very vague so I’ll be answering any questions you may need.
Thanks!
Line Trace is your saver, it scans via collision system if there something in the way of specific line (for example, from you POV to point ahead of POV). From hit data you can get Actor object and from there you can call some function in it, like open door.

If you want to animate something on level Matinee seems quite cave man way of doing it as it made for cutscenes, most optimal way is to make animated mesh, alternatively use blueprint timelines.
