math.CubicBezier
Example
Demonstrates the use of this function.
local points = {
Vector( 128, 128 ),
Vector( 384, 128 ),
Vector( 384, 384 ),
Vector( 128, 384 )
}
hook.Add( "HUDPaint", "math.CubicBezier", function()
local frac = RealTime() % 1
local point = math.CubicBezier( frac, points[1], points[2], points[3], points[4] )
surface.SetDrawColor( 255, 255, 0 )
surface.DrawRect( point.x - 4, point.y - 4, 8, 8 )
surface.DrawRect( points[1].x - 4, points[1].y - 4, 8, 8 )
surface.DrawRect( points[2].x - 4, points[2].y - 4, 8, 8 )
surface.DrawRect( points[3].x - 4, points[3].y - 4, 8, 8 )
surface.DrawRect( points[4].x - 4, points[4].y - 4, 8, 8 )
end )
