Code Example

The following example code creates a virtual crt screen and renders a circle at its center:

Import mojo2
Import crt

#GLFW_WINDOW_TITLE="crt example"
#GLFW_WINDOW_WIDTH=640
#GLFW_WINDOW_HEIGHT=480

Class MyApp Extends App
    Field canvas:Canvas
    Field crt:GraphicsCRT
    
    Method OnCreate()
        canvas = New Canvas
        
        ' initialize crt screen:
        crt = New GraphicsCRT(160, 120)
    End
    
    Method OnRender()
        ' clear screen and render circle:
        crt.Canvas.Clear()
        crt.Canvas.SetColor(1, 1, 1)
        crt.Canvas.DrawCircle(crt.ResolutionX/2, crt.ResolutionY/2, 50)
        
        ' draw crt screen on main canvas:
        crt.DrawScreen(canvas, 0, 0, DeviceWidth(), DeviceHeight())
        
        canvas.Flush()
    End
End

Function Main()
    New MyApp
End
