Hi, so i made another post but i feel like i was missing some information.

How would i go about finding “P” location from two vector where P is the corner im trying to find in 3D World space
The rotation of “A” is forward, thats where im trying to find the corner based on where “B” is

Image 1 is where “A” has 0, 0, 0 in rotaiton and Image 2 is where “A” has a rotation of “45”.
Let me know if you need any other information, i have also included an image for visual.

I used random point in space, but you use your own. Explanation:

The first two inputs are vector start and end. In your case you get the origin as start, and origin + forward vector multiplied by a generous float, because it must go far to actually intersect the plain.

This is a bit trickier since we don’t use the second vector, but we construct a plane from it. Plane origin may be either start or end of the second vector, and the subtraction order doesn’t matter; what matters is the vector you use for Cross Product. If it’s top-down view, it should be (0,0,1); if it’s side view, like in my case, it’s (0,1,0). So it depends.

So basically it constructs a virtual plane and calculates where your vector intersects it. Profit!

Hi thanks for the feedback, appricate it!
Another method, wouldn’t it be easier and more performance friendly by using colliders? with a trigger event on overlap etc?

There should be another easier approch, must be right? Let me know if anyone has another method?

I don’t know if you know blueprintUE.com, you can copy and paste the nodes there and it should keep all the nodes info and it saves you a lot of time if compared to taking screenshots

Absolutely, I find it really useful! It’s not about copy-paste, it’s just better in terms of readability.

I really care about learning and not just copying stuff, I don’t think that having to rewrite each step watching a small picture improves my understanding, personally I like to study and rearrange blueprint nodes directly from the editor (especially when I don’t have a second monitor available, in fact i bookmarked your post to better look at it later)

I’ve been watching it since it was created, even have it marked to receive notifications. Truth is it’s a lot of work to create the round corner logic just for the sake of it lol.
