    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.


This is a plug-in for Unreal Engine 4 that grants your projects the ability of Input Buffering which is commonly found in action and fighting games. While a controlled character is carrying out an uninterruptible action, buffering user’s input in the meanwhile instead of just ignoring it will make your games greatly more responsive to the player.

In addition, the plug-in features Command Recognition, which enables key combinations in your games. With that, you can even add complex input commands such as Quarter-Circle-Forward Punch.

Besides, you can draw input history like practice modes in many fighting games. A thumbnail renderer for Input Commands is also available to make them much more distinguishable by visualization in the editor.
