CoalObject

✗ from coal import CoalObject

Simple collision check between two identical boxes.

import coal # Create a box collision object box = coal.Box(1, 2, 3) obj = coal.CollisionObject(box) # Perform collision check res = coal.collide(obj, obj, coal.CollisionRequest()) print(res.is_collision)

Debug

Known issues

breakingIn coal-library v3.x, the main module is imported as `import coal` not `import coal_library`. The PyPI package name differs from the import name.

fix

Use `import coal` and `from coal import ...` for all symbols.

affects: >=3.0.0

gotchaCollision objects require explicit transform updates; transformations are not automatically applied after creation.

fix

Set the transformation using `obj.setTransform(transform)` before calling collide or distance.

affects: all

deprecatedThe `CollisionRequest` and `DistanceRequest` constructors now require keyword arguments for flags and settings; positional arguments are deprecated.

fix

Use `coal.CollisionRequest(enable_contact=True)` instead of `coal.CollisionRequest(True)` .

affects: >=3.0.0
