Okay I got my animate.bb and my png image in the same folder, saved before running it, also checked that the names match on the code and on the file name, but it says "image could not be found" and says it's this that causes it:

DrawImage img_object,x.y on the code.. how come this be possible, while everything is correct?

@MrTheflashback check your version of blitz3D, png image loading got introduced after the first version. Change the image to a bmp image if need be.

Would you recommend me to do computing in college which which contains programming? Is it difficult? Thanks!

[amcadam26]

@BengizSJ programming not difficult, it's all about problem solving, the coding side of it's normally pretty straight forward. It's just figuring out how to get round the problems you have, being good at maths helps.

Help!!! when i test it it says: Image does not exist. what is wrong? i typed: Graphics 640,480,16,2 img_object = LoadImage("Bildtilltest.png") x = 50 y = 350 SetBuffer BackBuffer() For z = 0 To 300 Cls DrawImage img_object,x,y x = 50 + z Flip Next End is it somthing wrong?

@alexrenfors you need to make sure the image in the same folder as the code. Save the code to the folder where the image is and then run it. Otherwise, check that you have the latest version of Blitz, older versions do not support png format images.

@MrTheflashback it could be that you did x.y instead of x,y?

@amcadam26 What grade at GCSE would be ok for me to attempt programming. Currently I am at a grade B and quite close to an A.

@19frank07 Make sure the image is saved in the same folder as the program.
