Sample image (pika.bmp) is provided in the /resources folder. Image should be grayscale with shape blocked in white color and background (area to be clipped) in black. To use auto trace, select "Shape From Bitmap" from "Create Shape" dropdown. Concave shape is decomposed to array of convex shapes, as Box2d supports only convex shapes Auto TraceĬoncave Hull generation to create shapes from bitmap image easily. Mark Bayazit's Algorithm is used to decompose concave shapes. To create rope joint, select two bodies -> create rope joint.To create prismatic joint, select two bodies -> create prismatic joint.To create gear joint, select two bodies and either two revolute or two prismatic joints or one revolute and one prismatic joint -> create gear joint.
To create distance joint, select two bodies -> create distance joint.JOINT_ROPE // distance between two bodies can be constrained JOINT_PRISMATIC // a body's translation can be constrained along an axis (localAxis) Joint. JOINT_GEAR // a body can drive another body using either revolute/prismatic joint Joint. JOINT_PULLEY // bodies suspended from pulley Joint. JOINT_REVOLUTE // bodies can rotate about localAnchorB Joint. JOINT_WELD // bodies are glued to each other Joint. JOINT_DISTANCE // fixed distance between bodies Joint.
