| Draw a circle. | |
| void(*) | DrawSolidCircleFcn (b2WorldTransform transform, b2Vec2 center, float radius, b2HexColor color, void *context) |
| Draw a solid circle. | |
| void(*) | DrawSolidCapsuleFcn (b2Pos p1, b2Pos p2, float radius, b2HexColor color, void *context) |
| Draw a solid capsule. | |
| void(*) | DrawLineFcn (b2Pos p1, b2Pos p2, b2HexColor color, void *context) |
| Draw a line segment. | |
| void(*) | DrawTransformFcn (b2WorldTransform transform, void *context) |

| float | jointScale |
| Global scaling for joint drawing. | |
| bool | drawContacts |
| Option to draw contact points. | |

| Draw anchor A for contact points (instead of anchorB). | |
| bool | drawShapes |
| Option to draw shapes. | |
| bool | drawChainNormals |
| Option to draw chain shape normals. | |
| bool | drawJoints |
| Option to draw joints. | |
| bool | drawJointExtras |
| Option to draw additional information for joints. | |
| bool | drawBounds |

| void * | context |
| User context that is passed as an argument to drawing callback functions. | |
This struct holds callbacks you can implement to draw a Box2D world.
Callbacks receive world coordinates. In large world mode the translation is double precision so it stays accurate far from the origin. Shift into your own camera frame inside the callbacks. Initialize with b2DefaultDebugDraw.
| void(*) b2DebugDraw::DrawBoundsFcn(b2AABB aabb, b2HexColor color, void *context) |
Draw a bounding box.
With double precision enabled, the single precision bounding box gets increasing padding when moving far from the origin.
