Platformer

Here's an example of a simple platformer parkour with components:

reset(); -- Add `reset` function from the samples so this works

-- Add box for player

local player = Scene:add_box({
    name = "player",
    position = vec2(2, -19.5),
    size = vec2(0.5, 0.5),
    is_static = false,
    color = 0xa0a0ff,
});

print(player.guid);

local hash = Scene:add_component({
    name = "Player Component",
    id = "@amytimed/test/player_component",

    code = [[
        local speed = 5;
