# # Linear Interpolation. # # Move the mouse across the screen and the symbol will follow. # Between drawing each frame of the animation, the ellipse moves # part of the distance (0.05) from its current position toward # the cursor using the lerp() function # # This is the same as the Easing under input only with lerp() instead. # attr_reader :x, :y def setup size(640, 360) no_stroke end def draw background(51) # lerp() calculates a number between two numbers at a specific increment. # The amt parameter is the amount to interpolate between the two values # where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 # is half-way in between, etc. # Here we are moving 5% of the way to the mouse location each frame @x = lerp(x, mouse_x, 0.05) @y = lerp(y, mouse_y, 0.05) fill(255) stroke(255) ellipse(x, y, 66, 66) end
