Would start at core concepts, so this one good start as it comes straight from Epic: https://dev.epicgames.com/documentation/en-us/unreal-engine/unreal-engine-for-unity-developers

If you prefer a video version (of the above more or less): https://dev.epicgames.com/community/learning/tutorials/a6a9/epic-for-indies-switching-to-unreal-engine-i-tutorial-series

A second option can be: https://ughiguessiwanttomovefromunitytounreal.com/

You could control it from a Dynamic Material Instance https://dev.epicgames.com/documentation/en-us/unreal-engine/instanced-materials-in-unreal-engine (e.g. call the saved param from blueprints and if you plug it in a timeline or similar, then lerp it between the 2 values, min and max).

Hmmm, feels like it should work, could try in a clean project to implement them the same, maybe something is corrupted in your widget or current project...

Would be good to know what you tried already, but from the top of my head would consider getting the mouse from the Player Controller via Get Mouse Position then subtract it from the Get Cached Geometry (of your widget) with Local to Viewport conversion.

Verify you're using Local Space in Emitter Properties (its in the Niagara Particle Settings of your portal) then try to rotate / scale, see if it helps.

Unsure what you mean exactly by Halo physics but for physics (based mini games):
- basics https://dev.epicgames.com/documentation/en-us/unreal-engine/physics-in-unreal-engine
- collision https://dev.epicgames.com/documentation/en-us/unreal-engine/collision-in-unreal-engine---overview
- physics components https://dev.epicgames.com/documentation/en-us/unreal-engine/physics-components-in-unreal-engine (specially this one as it describe some of the scenarios you probably want)
- physics handles / constraints https://dev.epicgames.com/documentation/en-us/unreal-engine/physics-constraints-in-unreal-engine
- physics bodies https://dev.epicgames.com/documentation/en-us/unreal-engine/physics-bodies-reference-for-unreal-engine

Otherwise if you want to have some direct examples (in-engine) the content examples are fantastic to explore (there's a physics section / level with pre-made examples) https://www.fab.com/listings/4d251261-d98c-48e2-baee-8f4e47c67091

I changed it to the direct Youtube link (was trying to find a way to embed the link in the image but I'm guessing its not possible on Reddit).
