Make 2D games.
Ship them everywhere.

Rayzr is a 2D game engine with a complete editor: build scenes from nodes, script them in Lua that reloads while the game runs, design levels with a built-in LDtk editor, and export to macOS, Windows, Linux and the web.

Scripting

Lua that reloads while you play

Gameplay is plain Lua 5.4. Save a script and the running game picks it up - no restart. The built-in Code tab knows the whole engine API: completion, hover docs, go to definition, rename across files and a debugger with breakpoints.

• Script properties show up in the Inspector
• Signals connect events to methods with a drag
• Every API function documented, with an example

The scripting guide

scripts/coin.lua

-- A coin: the player touching it collects it.
local Coin = {}

function Coin:on_body_entered(other)
    if self.taken or not other:has_tag("player") then return end
    self.taken = true
    Scene.find_node("HUD"):get_script():add_coin()
    -- A little hop as it goes.
    local x, y = self.node:get_position()
    Tween.to(self.node, "position", Vec2(x, y - 10), 0.2, "out_quad",
        { on_complete = function(n) n:destroy() end })
end

return Coin
