![[Game of Purpose] Day 46 – Simple Battery System](https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fm97fqv82toma4ni8smx3.png)
Today I implemented a simple battery system. It has a status indicator in the top right corner. It has a configurable rate of depletion and automatically turns the engine off when it runs out of power.
First I create a BPC_Drone_Battery component. It has an event DrainTick called every TickEvery amount of time and calls a Drain Charge function.
Drain Charge function simply takes Drain Per Tick away from a total charge and calls Update Charge. It does nothing when the battery is off.
Update Charge updates the Charge variable and calls events: Battery Charge Changed or when it drops to zero Battery Charge Depleted.
