in Contributed Library Questions • 1 year ago

Hi guys, first post here. I'm trying to upload a gif into my project. I downloaded the library, imported it, and imported the gif. however, when i run this code, it says "NullPointerException" at line 9. I'm relatively new to programming so any help would be appreciated

import gifAnimation.*;
Gif SonicRunGIF;
void setup()
{
size(500,500);
SonicRunGIF = new Gif(this, "SonicRunGIF.gif");
}
void draw()
{
image(SonicRunGIF,0,0);
}

Is there really a file with named "SonicRunGIF.gif" in you data-folder? If not, that would throw exactly that error.
And just an advice, usually variable names should begin with lowercase-characters, and Class-names with capitals.
That helps to understand your code and to avoid mistakes.

Did you call play() or loop() on the gif?
Have look into the "gifDisplay"-example, that came with the library.
