2D collision detection and resolution for circles, boxes, and polygons is handled by calculating overlaps and penetration depth using narrow-phase detectors like aabbContact, circleContact, and polygonContact. The system then applies appropriate physical responses to push objects apart.
Broad-phase collision detection uses a SpatialGrid to efficiently query nearby bodies and prune unnecessary checks, while narrow-phase collision detection determines exact overlaps and penetration depth between specific shapes. Combining both reduces computation for high-performance simulations.
Collision resolution to push objects apart and slide them is implemented via the resolvePass function. This function builds the SpatialGrid, queries nearby bodies, determines overlaps, and calculates the appropriate collision responses to apply.
Yes, this collision detection system is specifically designed for deterministic simulations within FS.GG UI products. It integrates with FS.GG Game.Core to ensure objects interact realistically and according to physical laws in a two-dimensional space.
Yes, you can use spatial partitioning to improve performance through the built-in SpatialGrid broad-phase mechanism. It efficiently prunes unnecessary narrow-phase computations, making it suitable for deterministic and high-performance simulations.
The SpatialGrid handles broad-phase collision pruning to reduce narrow-phase computations for box, circle, and polygon shapes. It is optimized for high-performance 2D simulations within the FS.GG Game.Core architecture rather than arbitrary non-2D spatial configurations.
