TUTORIAL:USING INPUT The easiest way to know if the user is pressing a key is calling the love.keyboard.isDown method, which has the following syntax: love.keyboard.isDown( key ) The key parameter is a string representing the key we want to see if it's currently pressed. A simple example: if love.keyboard.isDown( " " ) then text = "The SPACE key is held down!"end.
DEBUG - LOVE
From the Lua Reference Manual: . Enters an interactive mode with the user, running each string that the user enters. Using simple commands and other debug facilities, the user can inspect global and local variables, change their values, evaluate expressions, and so on. A line containing only the word cont finishes this function, so that the caller continues its execution.TUTORIAL:ANIMATION

Tiny-ecs is an Entity Component System for lua that's simple, flexible, and useful. Because of lua's tabular nature, Entity Component Systems are a natural choice for simulating large and complex systems. In game programming, ECS is a great way to simplify the game loop.

A ParticleSystem can be used to create particle effects like fire or smoke. The particle system has to be created using love.graphics.newParticleSystem.Just like any other Drawable it can be drawn to the screen using love.graphics.draw.You also have to update it in the update callback to see any changes in the particles emitted..
