Hi all

After trawling through the forums I have found exactly what I was looking for (written by Mark) not so long ago. Unfortunately, it doesn't work with the new data buffer stuff and I cannot find any examples of the loading async in the help?

Have I missed it and could someone kindly point me in the write direction please. Thanks

Import mojo

Class MyApp Extends App Implements IOnLoadImageComplete

	Field image:Image

	Method OnCreate()
		LoadImageAsync( "http://www.monkeycoder.co.nz/img/logo/cute/monkey1.png",,,Self )
		SetUpdateRate 60
	End
	
	Method OnUpdate()
		UpdateAsyncEvents
	End
	
	Method OnRender()
		Cls
		DrawText "Hello World!",0,0
		If image DrawImage image,DeviceWidth/2,DeviceHeight/2
	End
	
	Method OnLoadImageComplete:Void( image:Image,path:String,source:IAsyncEventSource )
		If image Print "OK!" Else Print "ERR"
		Self.image=image
	End

End

Function Main()
	New MyApp
End

for me it works (html5 target,v72b)

Import mojo

Class MyApp Extends App Implements IOnLoadImageComplete

	Field image:Image

	Method OnCreate()
		LoadImageAsync( "http://www.monkeycoder.co.nz/img/logo/cute/monkey1.png",1,Image.MidHandle,Self )
		SetUpdateRate 60
	End
	
	Method OnUpdate()
		UpdateAsyncEvents
	End
	
	Method OnRender()
		Cls
		DrawText "Hello World!",0,0
		If image Then DrawImage image,DeviceWidth()/2,DeviceHeight()/2
	End
	
	Method OnLoadImageComplete:Void( image:Image,path:String,source:IAsyncEventSource )
		If image Then Print "OK!" Else Print "ERR"
		Self.image=image
	End

End

Function Main()
	New MyApp
End

Interesting.
I get "BBThread is private" and the error highlights

Class AsyncImageLoaderThread Extends BBThread="BBAsyncImageLoaderThread"

in the module asyncimageloader.monkey

This is with version 75D

Interesting to know that it works for you, so I will try some other versions. Thx for the info

Just to confirm. The code works in 74a but not onwards including 76a.I know these are experimental builds, but thought it was worth noting.

edit:
yes,can't get it to work in v76a for html5 or glfw :-(

Class AsyncImageLoaderThread Extends BBThread="BBAsyncImageLoaderThread"

that's a bug. it should be "Extends Thread".

also, http image pathing only work with html5, flash. not glfw. you'll need to send an httprequest and build a small routine for that to work in glfw.
