  • Supported Platforms
  • Supported Engine Versions
    4.25 - 4.27
  • Download Type
    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

When using the default overlapping detection methods, even with colliders, if the speed or the animation is too fast, the intended collision can be skipped entirely.

This is the case for small bullets against thin targets or weapon swinging animations that are too fast or scattered.

This system allows you to trace between positions and determine if something was hit.
