Tiled Background Broken Texture when loading From URL:

[Tarek200]

If two different objects request the same image to Load from URL, the Tiled_BG will load with a broken Texture. In this case, I load a (Sprite & TiledBG)

If you delete the first Action that loads the Sprite from URL then the Tiled Background will load as intended.

Attach a .c3p

If you disable loading the Sprite image first it works correctly. The problem is the Sprite loads the image as a non-tiled texture, and then the Tiled Background loads the very same texture but set to tiled mode; currently the entire asset management system in Construct only handles textures by URL, so in that case it identifies it's already loaded the same texture and returns a non-tiled one to Tiled Background.

This could be difficult to fix as it may involve a significant overhaul of the asset management system in order to fix this one edge case with texture loading. Is it really important for your project?

This works well if done through scripts.

@AshleyScirra Is not a big deal for me as I haven't used it in anything important, except for editors etc... So is okay for me. Though from what you described is first come first served so I changed the order of the Actions if you load first the TileBG and then after the Sprite it looks like it works correctly unless something happens underhood that I dont know I think that could be a quick fix, I will just have to remember this edge case.

@WilsonPercival Cool Thanks, nice to have alternatives just in case.

Closing as wontfix as this is appears to be a difficult problem that does not have any real-world use yet.
