MCBE Studio
Mod called “MCBE Studio” for Minecraft Bedrock version 1.12 allows you to use time intervals in the game version. The mod’s API is simple, it cannot be compared to more serious add-ons, but with its help, you can place keyframes in the world that interpolate to create a sequence.
In the graphical interface of Minecraft, there is a button “Open Mcbe Studio”. Due to the lack of event handlers in the API, currently the only way to open the main interface is to open any game interface (pause, inventory, chat…), direct the mouse cursor to where the button is located, and exit the interface using a keyboard combination.
The main interface contains several buttons:
Below the timeline, there are several buttons to navigate to the previous and next frame, as well as to the first and last. There is also a play/pause button and an unused button that will allow you to play the sequence without the interface.
In keyframe mode, punch the armor stand in front of you to place a keyframe, exit keyframe mode, then stop and turn to punch another.
