== a Player ==
We test our Gideros Game Template1 and add a player you can control with the keyboard.

 '''Note: this is for testing purposes only'''

I didn't really know where to put the code so I chose to create a file called "''player1.lua''" in the '''gfx''' folder.

The '''Player''' Class will mainly consist of:
* a Sprite (a Pixel)
* some vars
* controlling the player using the keyboard

The code:
<syntaxhighlight lang="lua">
Player1 = Core.class(Sprite)

function Player1:init()
	self.sprite = Pixel.new(math.random(0xffffff), 1, 32, 64)
	self.sprite:setAnchorPoint(0.5, 0.5)
	-- some vars
	self.x = 0
	self.y = 0
	self.speed = 32*6
	self.vx = 0
	self.vy = 0
	self.sx = 1
	self.sy = 1
	self.w = self.sprite:getWidth() * self.sx
	self.h = self.sprite:getHeight() * self.sy
	self.flip = 1
	-- position
	self.sprite:setPosition(self.x, self.y)
	-- order
	self:addChild(self.sprite)
	-- let's go
	self:myKeysPressed()
end

-- keys handler
function Player1:myKeysPressed()
	self:addEventListener(Event.KEY_DOWN, function(e)
		-- movements
		if e.keyCode == KeyCode.LEFT or e.keyCode == g_keyleft then self.isleft = true end
		if e.keyCode == KeyCode.RIGHT or e.keyCode == g_keyright then self.isright = true end
		if e.keyCode == KeyCode.UP or e.keyCode == g_keyup then self.isup = true end
		if e.keyCode == KeyCode.DOWN or e.keyCode == g_keydown then self.isdown = true end
		-- actions
		if e.keyCode == g_keyaction1 then self.isactionpunch1 = true end
		if e.keyCode == g_keyaction2 then self.isactionpunch2 = true end
		if e.keyCode == g_keyaction3 then self.isactionpunch3 = true end
	end)
	self:addEventListener(Event.KEY_UP, function(e)
		-- movements
		if e.keyCode == KeyCode.LEFT or e.keyCode == g_keyleft then self.isleft = false end
		if e.keyCode == KeyCode.RIGHT or e.keyCode == g_keyright then self.isright = false end
		if e.keyCode == KeyCode.UP or e.keyCode == g_keyup then self.isup = false end
		if e.keyCode == KeyCode.DOWN or e.keyCode == g_keydown then self.isdown = false end
		-- actions
		if e.keyCode == g_keyaction1 then self.isactionpunch1 = false end
		if e.keyCode == g_keyaction2 then self.isactionpunch2 = false end
		if e.keyCode == g_keyaction3 then self.isactionpunch3 = false end
	end)
end
</syntaxhighlight>

== Code comments ==
In init we make our player1 be a Pixel.

We set various variables which we will update in the '''Game''' scene ('''LevelX''') to reflect the user input.

=== keys handler ===
This is where the key remapping system shines :-)

== Next? ==
Well that's it for this Gideros Game Template1 tutorial.

This is now yours to use/modify (add scenes, ...).
