Is it possible to read the collision polygon points?

I'm mostly talking about sprites. Is there a way to read the collision polygon points similar to how you can read image points?

For example on a sprite, you can do ImagePointX and ImagePointY. I don't see any expression like this for collision polygon points.

If not that would be an excellent new feature.

Darn. Would anyone else besides me find it extremely useful to read the collision polygon points?

What do you need it for? I've never heard anyone ask about this before.

I would, sometimes you want to show polly even for the end game user.

You could put an image point at each polygon point if you need to, but it would be easier to have access.

I would, sometimes you want to show polly even for the end game user.

But why though?

Given how limited our resources are we need a good justification for any feature. The collision poly seems like an internal game detail that you wouldn't show to the user.

in some games the player does "editing" too.

I have a game where the player builds his ship out of parts. Some of those parts are armor and he wants to know while he is building his ship in game--how much is cosmetic and what is the real pollygon?

I could make up collision polygon shaped sprites and show that or put image points on pollygon points and draw lines or--you could tell me where the polygom points are.

There are work arounds--just sometimes you want to know where they are. For me it would not be a high priority--but since you asked thats why.

Colludium's plugin has collision point detection, and visible collision mask as well. You can ask him if it will help in your particular case.

I also asked the same thing a long time ago.

My idea was for a car game.

The car was in a mud zone and if the player accelerated then the car sank into the mud zone, for that he had to move / create a collision point in the mud in the wheel area and move it down to make The car sinks.

The LFJS plugin allows you to edit the collision polygon for the box2d physics engine (so you can create shapes on the fly).

I made a plugin for c2 that did this (a long time ago); I'll convert it to c3 soon.

I made a demo for another post where I used image points for detecting the exact point of collision:
