Multi-layer Background

Post by kirkdev » Fri Jun 21, 2019 5:37 pm


My name is Kirk. I have just started playing around with Love2D, maybe for 2 weeks or so now. I was impressed at how quick I was able to put something together and completed a small shooting gallery game in a single evening.
The attachment ShootingGallery.png is no longer available

I am now going to complete a slightly bigger project in which it has multiple images used as the background to create a parallax effect. I seem to be having problems of the bat just loading these images. I have attached the 2 of the 4 layers I am using for the background 1-4 in which the order they should be drawn.

I am getting a black background and no errors. After further investigation it looks like image 1 loads and can be drawn just fine but the other 3 do not load at all.

Is there some issue with loading images which have alpha?

There is no problem with loading and drawing images that have alpha transparency. Just use the normal image loading function You can take a peek at my example if you like (big thanks to PWL for the images).

If the images are too big, you might be running out of texture memory; sadly, without you sharing all the necessary information (code and assets, but preferably as a .love file of a minimal example where it still happens), the only thing we can do is just guess.
