    引擎插件
    此产品包含一款代码插件,含有预编译的二进制文件以及与虚幻引擎集成的所有源代码,能够安装到您选择的引擎版本中,并根据每个项目的需求启动。

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.

The difference between this and the free plugin is that this actually comes with a complete set of parameters to use with cross-linking tracing methods. This means you will have less chances of missing the target.

The difference between this and the blueprint plugin is performance. This can be used extensively on multiple objects whereas with blueprints, it's way more costly and limited.
