math.BSplinePoint
Example
Example usage of the function, makes a black box moving along the beizer curve made out of 4 points.
local points = { Vector( 100, 100, 0 ), Vector( 200, 200, 0 ), Vector( 300, 100, 0 ), Vector( 400, 200, 0 ) }
hook.Add( "HUDPaint", "BSplinePointExample", function()
-- Draw the points
for _, p in ipairs( points ) do
draw.RoundedBox( 0, p.x - 2, p.y - 2, 4, 4, color_white )
end
-- Draw the spline
local pos = math.BSplinePoint( ( math.cos( CurTime() ) + 1 ) / 2, points, 1 )
draw.RoundedBox( 0, pos.x - 2, pos.y - 2, 4, 4, Color( 0, 0, 0 ) )
end )
