2D Point Within a 2D Triangle

[Sleeve]

I just thought some of you might like a function that determines if a 2D point exists within a 2D triangle.

In this case, I have restricted the dragging of an MC to within the bounds of a triangle using this function.

My next move is to constrain dragging to the outermost edges of a triangle, square, pentagon, etc...

Anyone able to contribute?

Is this, what you are searching for ?

try the 'com' version. for convex polygons only.

Sweeettt. I've searched for this far and wide. thank you!

You are either way above the average intellegence or you have a hekc of a lot of time on your hands....wow!

here is a small bugfix - did you find it ?

no big deal here. I thought about this solution, while thinking about the distance from a point to a polygon. It's the same technic.

yes, this is no big deal but the other examples on your websites are great. Good work.

One suggestion if I may.

Use this.onMouseMove and add a updateAfterEvent() at the end of your function to make it frame rate independent. As you may know, it's a smoother motion at any framerate.
