Issues with Blitting

[Kameku]

Okay, so, in my code, I have a segment that looks like this:

Code: Select all

drop = Image.load("gui/dropper.png")
crange = Image.load("gui/colors.png")

And then later, I have a part that looks like this:

Code: Select all

screen:blit(353,240,drop)
screen:blit(383,240,crange)

BUT, when I run the prog on Windows LuaPlayer, it flashes, and creates a file named "luaplayer.exe.stackdump", which contains

Code: Select all

Stack trace:
Frame     Function  Args
0022EEA8  007F48D6  (00000000, 00000000, 0040C9BE, 0022EF1A)
0022EEE8  0040CB66  (00000002, 10030EF8, 10030090, 610A5E22)
0022EFD8  61004DD2  (0022EFF0, 000F000E, 00110010, 00130012)
0022FF88  6100594F  (00000000, 00000000, 00000000, 00000000)
End of stack trace

But, when put into comments, all my other images blit fine. Why?

ok i cant tell you completely how to fix it unless u show me your whole script. but the way to stop the screen flashing like that is to add a screen.waitvblankstart(number goes here) somewhere

That should solve ur problem

[JorDy]

Lua IS case sensitive so its

screen:waitVblankStart([number])

Oh, sorry, I figured out the problem ages ago. >_> I had made the image, and for some reason, my computer saved it as "crange.png.bmp"

Thanks for the input, though. :]
