Grid (game engine)

Grid lets you jump straight into game logic.

Making a HUD element

class "gui.hudhealth" ( "gui.panel" )
local hudhealth = gui.hudhealth
function hudhealth:draw()
    love.graphics.print( localplayer:getHealth() )
    gui.panel.draw( self )
end

Making an entity

class "npc_monster" ( "npc" )
function npc_monster:npc_monster()
    npc.npc( self )
    self:setSprite( "images/monster.png" )
end
entities.linkToClassname( npc_monster, "npc_monster" )

Playing a sound from an entity

function npc_monster:onTakeDamage()
    npc.onTakeDamage( self )
    self:emitSound( "sounds/cry.wav" )
end
