Here you will find various resources to help you create games and apps in Gideros Studio.

note: you may have to provide your own assets (fonts, gfx, …)

Description

Here are two classes which allow you to control your player, on your mobile device, using touch buttons.

It has 4 buttons: right, left, A, B but you can add more.

note: the first class uses the UI_Buttons#Button_with_Text class, but you are free to use any other kind of buttons

Sample image:

Mobile Controls Class (first option)

This is the first option to add mobile controls to your game.

function Mobile:init(xplayer1)

	self:addChild(mybtnright)
	local mybtnleft = ButtonText.new("<", nil, 0xffffff, 12, 8)

Usage

Whichever above options (class) you choose they work the same, you pass your Player class as an argument to the Mobile class. 

	-- mobile controls
	local mymobile = Mobile.new(self.player1)
	self:addChild(mymobile)
