How to find custom shape coordinates for physics

Solar2D General Questions/Discussion
#1

I want to construct complex physic bodies.

Is there a way to find x,y coordinates for each seperate body without a paid software?

For example suppose I have a car and want to break it down to 5 bodies (1 for main car, 4 for the wheels)

How can I find the coordinates of each seperate body?

Also does it matter what the size of the picture is?

Thanks in advantage

Hi @ant_settas,

In a basic image editor, you could use your “1x” (game size, non-scaled) art and work from the center of each body, checking how many pixels away from center is each corner point. Then, just test, test, and test again using the physics “hybrid” view to check how accurate it is, and make minor adjustments from there.

There was a handy plugin for Adobe Fireworks at one point, which would let you trace an image with the pen tool and get the physics points, but that of course would require Adobe Fireworks (not free).

Best regards,

Brent
