MX2 first library

1 August 2016 - General , monkey - by degac - No Comments

I’ve decided to ‘translate’ in BlitzMax the Mojo commands, just to type a little less 😀

Basically every single methods in mojo.graphics has been wrapped in a ‘basic’ function like DrawLine() or DrawRect() instead of using canvas.DrawLine() or canvas.DrawRect()

The only difference is the need of use a SetCanvas(canvas) call to setup the ‘default’ canvas where all the graphics functions are directed.

'Main.monkey2

#import "lib/lib_mojo.monkey2"		'helper
#Import "<std>"
#Import "<mojo>"

Using mojo..

Class MojoTest Extends Window
	Global timer:Timer
	
	Method New()
		ClearColor=New Color( 0,0,.5 )
		timer=New Timer(60,OnUpdate )'calls the refresh at 60 Hz
	End 
	
	Method OnUpdate()
			App.RequestRender()
	End 
	
	Method OnRender( canvas:Canvas ) Override
			SetCanvas(canvas)
			SetColor(Color.White)		
			
			DrawTriangle(100,100,200,100,150,150)
			SetColor(Color.Red)
			SetAlpha(.5)
			DrawRect(80,80,140,120)
			SetAlpha(1)
			SetColor(Color.White)
			
			Local r:Recti=GetViewPort()
			DrawText("ViewPort: "+r.X+" "+r.Y+" "+r.Width+" "+r.Height,320,20,.5,1)
			DrawText("HALLO",320,200,.5,0)

	End 


End Class

Function Main()
	New AppInstance
	New MojoTest
	App.Run()

End

Class MojoTest Extends Window

Method New()

ClearColor=New Color( 0,0,.5 )

timer=New Timer(60,OnUpdate )'calls the refresh at 60 Hz

End

Method OnUpdate()

App.RequestRender()

End

Method OnRender( canvas:Canvas ) Override

SetCanvas(canvas)

SetColor(Color.White)

DrawTriangle(100,100,200,100,150,150)

SetColor(Color.Red)

SetAlpha(.5)

DrawRect(80,80,140,120)

SetAlpha(1)

SetColor(Color.White)

Local r:Recti=GetViewPort()

DrawText("ViewPort: "+r.X+" "+r.Y+" "+r.Width+" "+r.Height,320,20,.5,1)

DrawText("HALLO",320,200,.5,0)

I think it’s more readable …

All the functions implements – when available – the different ‘version’, using overriding.

At the moment I’ve implement just ONE ‘special’ function (missinig in mojo standard) : TileImage

Probably I will add more function – if needed.

Building up this ‘library’ was an interesting way to understand MX2 syntax & features, like the new type Recti and Vec2f.
