Sizing a Game to Fit on Any Monitor

NoodleMan

So I have a game that I programmed on my own monitor and it apparently does not look the same on the monitors at school. I am confused as to how I would go about programming it to always appear the same way regardless of the monitor in use. I am sure there is an easy way to do this but I could use a push in the right direction.

Use displayWidth & displayHeight as arguments for size():

1. https://processing.org/reference/displayWidth.html
2. https://processing.org/reference/displayHeight.html
3. https://processing.org/reference/size_.html

For example: size(3*displayWidth/4, 3*displayHeight/4, JAVA2D);

Then make everything which draws on the canvas based on both width & height:

1. https://processing.org/reference/width.html
2. https://processing.org/reference/height.html
