# Examples

These examples are made from memory on how the engine works, if one of these examples do not work you could make an issue on the the [Issues Tab](https://github.com/pyudev-x/goblocks/issues)!

## Moving Sun

Let the sun move across the screen!

```lua
function Setup()
    Wow = newCircle()
    Wow:setPos({0, 110})
    Wow:setColor("yellow")
    Wow:setRadius(40)
    Where = 1
end

function Update(dt)
    if Wow:getPos()[1] > 880 then
        Where = -1
    elseif Wow:getPos()[1] < 0 then
        Where = 1
    end
end

function Draw()
    Wow:draw()
    local pos = Wow:getPos()
    pos[1] = pos[1] + Where*5
    Wow:setPos(pos)
end
```

## Moving Player

Setup a simple player to move around!

```lua
function Setup()
    Player = newPlayer()
    Player:setPos({660, 440})
end

function Update(dt)
    Player:setVelocity({0, 0})
end

function Draw()
    Player:draw() -- The player will automatically move when pressing -WASD-
end
```

## Hello!

The example you *might of* saw on the [README](./README.md)!

```lua
function Setup()
end

function Update(dt)
end

function Draw()
    hello()
end
```

## Growing Circle

Make a circle that will grow over time!

```lua
function Setup()
    Circle = newCircle()
    Circle:setRadius(1)
    Circle:setColor("lime")
end

function Update(dt)
    Circle:setRadius(Circle:getRadius()+1)
end

function Draw()
    Circle:draw()
end
```

## Sounds, Text and Input

Use sounds, text and input all together!

```lua
function Setup()
    Text = newText()
    Sound = newSound()
    Sound:loadSound("/path/to/sound")

    Text:setText("Sound played 0 times!")
    
    Times = 0
end

function Update(dt)
    if isKeyPressed("space") then
        Times = Times + 1
        Sound:playSound()
        Text:setText("Sound played " .. Times .. " times!")
    end
end

function Draw()
    Text:draw()
end
```
