Shorthairs Help

This will help when you are animating something on your scren , what it does is draws somthing to het screen and then draw the next frame to memory and then switches , so Front buffer to Back buffer , and the process is repeted

code:


Graphics 640,480

SetBuffer BackBuffer()

While Not KeyDown(1)

Flip

Cls

Line 100,200,320+100*Cos(a),240+100*Sin(a)

a=a+1

Wend


FLIP
is used to swap between the front and back buffer , this command tells the program to use hte next frame , It also refreshes your screen

This program draws a line from the center of the screen (100,200) at an angle of a degrees. we use sin and cos to get the angle
