Hi,
I need to create a window, where I'll draw an animated sprite.
I decided to use the "SetRenderToImage" function. Although it seems to work OK, I cannot place this window in a specific place on the screen
Here is my coding:

+ Code Snippet

windowImg = 1
windowSpr = 1

// set window properties
SetWindowTitle("Window")
SetWindowSize(1024, 1024, 0)
SetVirtualResolution(1024, 1024)

img = LoadImage("gem.png")
spr = CreateSprite(img)
SetSpriteAnimation(spr, 256, 256, 4)
frame = 0

windowImage = CreateRenderImage(256, 256, 0, 0)

SetSyncRate(10, 1)

Do

	SetRenderToImage(windowImg, 0)

	SetSpriteFrame(spr, frame)
	DrawSprite(spr)
	inc frame
	if frame > 4 then frame = 1

	SetRenderToScreen()

	CreateSprite(windowSpr, windowImg)
	SetSpritePosition(windowSpr, 256, 256)

	sync()

	SetRenderToImage(1, 0) 
	ClearScreen()


loop

Any help?

There's not much wrong there, just a typo.
you have set the variable windowImg but create an image in variable windowImage. After all you only use the empty windowImg.

Here is a slightly modified version

+ Code Snippet

//~ windowImg = 1
windowSpr = 1

// set window properties
SetWindowTitle("Window")
SetWindowSize(1024, 1024, 0)
SetVirtualResolution(1024, 1024)

img = LoadImage("gem.png")
spr = CreateSprite(img)
SetSpriteVisible(spr,0)
SetSpriteAnimation(spr, 256, 256, 4)
frame = 0

windowImage = CreateRenderImage(256, 256, 0, 0)
CreateSprite(windowSpr, windowImage)
SetSpritePosition(windowSpr, 256, 256)

SetSyncRate(10, 1)

Do

	SetRenderToImage(windowImage, 0)
	ClearScreen()

	SetSpriteVisible(spr, 1)
	SetSpriteFrame(spr, frame)
	DrawSprite(spr)
	inc frame
	if frame > 4 then frame = 1
	SetSpriteVisible(spr, 0)

	SetRenderToScreen()


	sync()

	//~ SetRenderToImage(1, 0)
	//~ ClearScreen()


loop
