when trying to load the background.png used in the BumbleBee tutorial; Upon launch i get this error:



It's the exact same "background.png", i simply renamed it to "bg.png" .

In following the Tier 2 tutorial, my code is as follows:



Everything else seems to work as expected ..

Check for case sensitivity, is it really "bg.png" or maybe "bg.PNG"???

Yes. However, turns out i'm quite the tosser

Apparently, when i was having my morning coffee, my brain somehow must have assumed they were both png's when copying the image..and thus decided to make my fingers type "mv background.jpg bg.png"

The 'background' is actually a jpg file , while the bumblebee sprite is png..

(which i guess would explain the "JPEG Error: 55" i got when trying to LoadSprite the converted (NOT)png-to-bmp ..)

FORGET YOU EVER SAW THIS! LOOK AWAY!

Yes

And should anyone who've, however unlikely, having made the same stupid mistake .. ffprobe is a nice tool to check actual format

In this case, the 'png' file proved itself being a jpg, since
Quote: "$ ffprobe game/media/bg.png"

gave
Quote: "Input #0, image2, from 'game/media/bg.png':
Duration: 00:00:00.04, start: 0.000000, bitrate: 3916 kb/s
Stream #0:0: Video: mjpeg, yuvj444p(pc, bt470bg/unknown/unknown), 1024x768 [SAR 72:72 DAR 4:3], 25 tbr, 25 tbn, 25 tbc
"

While an actual png image should return something like:
Quote: "Input #0, png_pipe, from 'game/media/bg.png':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: png, rgb24(pc), 1024x768 [SAR 2834:2834 DAR 4:3], 25 tbr, 25 tbn, 25 tbc"
