WTF!!! Why no image is displayed???

Import mojo2

Function Main()
    New MyGame()
End

Class MyGame Extends App

	Field canvas:Canvas
	Field img:Image

	Method OnCreate()
		canvas=New Canvas
		SetUpdateRate 60
		img=Image.Load("banco.png",0,0)
	End Method
	
	Method OnUpdate()
	End Method
	
	Method OnRender()	
		canvas.Clear()		
		canvas.DrawImage img,10,10		
		canvas.Flush()	
	End Method
End



Even if I change "canvas.Clear()" to "canvas.Clear(255,255,255)" just a black square - the image's size - is displayed on an white canvas.

If I run in HTML5 the image is displayed correctly.

It's working fine here. Are you sure it's actually loading the image? Because it sounds like it's just in the wrong place or has the wrong name. Have you tried a different image?


cgrossi(Posted 2016) [#3]
On HTML5 it's working fine...


ImmutableOctet(SKNG)(Posted 2016) [#4]
That's even weirder. Maybe it's a driver issue? Do the official examples work? They're located in "modules/mojo2/bananas".


cgrossi(Posted 2016) [#5]
yes, the examples work... don't know what to do.... :(

If you don't mind uploading the file, I could try it myself.

Is it possible you're using a file with the wrong file extension? For example, a JPG file named PNG, despite being the JPEG format. In HTML5's case, it doesn't really care what the format is, as long as the browser can load it.


cgrossi(Posted 2016) [#7]
no, no problem.. here go the code and images.. I'm thinking it's something with the image, because I copied one image from another sample and it did work fine, although my image is correct.

Okay, I'm not sure what's wrong, either. It's working on my machine, even under regular GLFW3:




cgrossi(Posted 2016) [#9]
with regular GLFW3 I can't run mojo2 and with mojo the image is displayed perfectly...


ImmutableOctet(SKNG)(Posted 2016) [#10]
Hang on, what about GLFW3+ANGLE, then? (Assuming you're on Windows)

By the way, what version of Monkey are you using?


cgrossi(Posted 2016) [#11]
I just can use mojo2 on GLFW3+ANGLE, not with GLFW. And I'm using the 85E.


ImmutableOctet(SKNG)(Posted 2016) [#12]
It doesn't display the image on GLFW3+ANGLE, then, right? Or does it only work with regular GLFW3?

As a side note, if regular GLFW3 doesn't work, it's probably due to bad OpenGL drivers. ANGLE on the other hand doesn't use OpenGL.

I'd say it could be a driver issue, but then again, your browser displays it fine, and you said the examples worked.

To be honest, I'm lost.


cgrossi(Posted 2016) [#13]
when I run mojo2 with GLFW3 only, I got this error: Memory Access Violation on that line:

	glGenerateMipmap GL_TEXTURE_2D


of method UpdateMipmaps (graphics.monkey)


ImmutableOctet(SKNG)(Posted 2016) [#14]
Sounds like a lack of OpenGL 3 support to me. Regardless, ANGLE should be working fine for you. I'm not sure why your image wasn't working, though. You could try messing around with the image flags, I guess.


cgrossi(Posted 2016) [#15]
I use Image.Filter and the image appear.. Figure it out... kkkkkkk Anyway, I'll do others tries. Thanks a lot.
