# Query physics colliders [Back to Use gameplay actions](https://rustic-game-engine.pages.dev/markdown/guides/gameplay-actions.md). Follow [Set up gameplay actions](https://rustic-game-engine.pages.dev/markdown/guides/gameplay-actions/setup.md) before running this Lua example. ```lua return { Start = function() local hit = Physics.sphereCast(Vector3(0, 4, 0), Vector3(0, -1, 0), 10, 0.25) if hit then print(hit.entity, hit.distance) end end } ``` `raycast(origin, direction, distance, ignore?)` returns the nearest hit or nil/null. `sphereCast` adds a radius and uses rounded sphere/box contacts; `overlap(center, radius, ignore?)` returns entity IDs. Hits contain entity, point, normal and distance. Direction is normalized by the engine. Queries use the simulation's authored primitive colliders represented by world AABBs, including parent transforms.
