How to create an energy to move system

Hi! This is my first tutorial and I’ll be showing you how to make a system where you need energy(or another item) to move. First place a questioner on the map and then place an item granter right beside it. [Home (2)] Connect the questioner to the item granter with a wire and set it to “Question answer correctly” → “grant item.” [Home (3)] Click on the item granter and set the item to grant to “Energy”(or your preferred item). Change the amount to grant to the amount of the item you want to …

The system could help everyone keep track on their amount of Energy they have via overlay, and could force to stop the player once the energy ran out.
