Projecting Vector using dot product help

[Everynone]

It has so many applications that, once you know how it works, there’s no looking back. Some examples:

Left Mouse button pressed and released equivalent in enhanced input (or drag and drop)

Here’s some script allowing for picking up stuff and moving it in a specific plane only we determine ourselves manually: [image] The green debug plane visualises what’s going on. In short: shoot a beam (trace) from the screen centre towards the projected mouse cursor, when it eventually intersects that plane (which is infinitely large), place the actor at the intersect world coordinate. If I change the normal: [image] You could derive this Normal from the actor itself instead: [imag…

Line Trace from a 3d point to mouse location

You’re tracing with a fixed distance of 500, replacing the projection’s X with a fixed value. It’s actually hard to imagine how that would look like, a strangely distorted / twisted undulating surface mayhaps? , for sure. I want this trace to stay on the same plane as my character, so the X value of the start point & end point should be the same. Consider the following: [image] create a virtual plane where the character is and point it towards X (Plane Normal 1,0,0) …
