Push-button doors in NodeCore

A short video showing my implementation of “automatic” doors controlled by a push-button in NodeCore. Pushing the button will toggle the doors (open/closed) and reset the button to its resting state. The mechanism is hidden to avoid spoilers. [NodeCore](https://content.minetest.net/packages/Warr1024/nodecore/) is a block-building game based on the [MineTest](https://www.minetest.net/) engine.
