MOAIImageTexture does not seem to be supported

[OliverHrdz]

With RapaNui, I'm not able to dynamically update a MOAIImageTexture object already bound to GPU memory from an input event handler. I display the texture with RNFactory.createImageFromMoaiImage () function, which accepts a MOAIImage object. MOAIImageTexture inherits from MOAIImage, so I expect that createImageFromMoaiImage () should work fine passed in a subclass of what it expects. This may be a bug somewhere, as MOAIImageTexture is something that has recently been added to MOAI. Thanks!

Code to reproduce:

require("rapanui-sdk/rapanui")

SCREEN_WIDTH = RNFactory.screen.width
SCREEN_HEIGHT = RNFactory.screen.height

print ( "hello" )
local background = RNFactory.createImage ( "images/background-blue.png" )
background:sendToBottom ()
print ( "displayed background" )

texture = MOAIImageTexture.new ()
texture:load ( "C:/dev/sdks/moai-sdk/samples/hello-moai/moai.png", MOAIImage.TRUECOLOR + MOAIImage.PREMULTIPLY_ALPHA )
print ( "loaded texture" )

-- demonstrate that we can modify the texture before rendering it
-- this draws a red line 50 pixels long diagonally from the top left
for i = 0,50 do
    texture:setRGBA ( i, i, 1, 0, 0, 1 )
end

image = RNFactory.createImageFromMoaiImage ( texture )
image.x = SCREEN_WIDTH/2
image.y = SCREEN_HEIGHT/2
print ( "displayed image from texture" )

function onTouchEvent ( event )
    if event.phase == "began" then
        print ( "touch begin" )

        -- this should draw a white line 128 pixels long diagonally from the top left
        for i = 0,127 do
            texture:setRGBA ( i, i, 1, 1, 1, 1 )
        end 
        texture:invalidate ()
    elseif event.phase == "ended" then
        print ( "touch end" )

        -- this should draw a blue line 128 pixels long diagonally from the top left
        for i = 0,127 do
            texture:setRGBA ( i, i, 0, 0, 1, 1 )
        end
        texture:invalidate ()
    end
end

local listenerId = RNListeners:addEventListener("touch", onTouchEvent)

Hi,

MOAIImageTexture is something that has recently been added to MOAI.

Yes, I've labeled this as "new feature". We'll check on this.

Have a nice day,
