Stick to using these standards!

Units

For physics, SI-units are preferred, with a conversion-factor to pixels. Realworld physics should be used whenever possible.

• 1m = 50px
• Acceleration: m/second^2
• Speed: m/second
• Dimensions: meter
• Time: seconds
• Angles: radians.
• Mass: gravitational acceleration in m/s^2.

Performance tips

• Don't use save() and restore(), rather just put the changed settings back to what they were before.
• Use integers for sprite coordinates wherever possible
• Pre-render/cache to in-memory canvases for minimizing redraws.
• Use prototypes for objects!
