Arc and Point Collision

Phaser 3
1

Does Phaser 3 have a math function to check a collision between a point and an arc?

I only know how to check a point collision with a circle which is by checking it’s distance to the circle center.

But now sure how to detect witn an arc. I tried Google but cannot find any.

Or can I use the Phase Arc polygon and check collision detection against a point? How would I do that?

If there is a simple math calculation that would be better.

Thanks.

If you go with generating your arc with polygon, you can probably use the Phaser.Geom. Polygon.ContainsPoint.

Thanks, but that will be a triangle (unless if I just add more points).

But, yes that can be an alternative solution.

I’m still figuring out if there is a feature in Phaser 3 I can use for an arc.

I believe, matterjs could work. But I’m trying to avoid using physics.

I don’t think so, because there’s no Phaser.Geom.Arc class.

I’m sure there’s an algorithm for this somewhere.

Thanks. I was just wondering if there were something in Phaser 3 engine I can use. Since there is none, then I will just use my own maths calculations. Thanks.
