Spritepoly

Spritepoly (Statement)​

Format​

spritepoly sprite_number, variable[]
spritepoly ( sprite_number, variable[] )
spritepoly sprite_number, { x1, y1, x2, y2, x3, y3 ... }
spritepoly ( sprite_number, { x1, y1, x2, y2, x3, y3 ... } )
spritepoly sprite_number, { {x1, y1}, {x2, y2}, {x3, y3} ... }
spritepoly ( sprite_number, { {x1, y1}, {x2, y2}, {x3, y3} ... } )

Description​

Create a sprite from a list of points that represent a polygon. The sides of the polygon are defined by the values stored in the array, which should be stored as x,y pairs, sequentially. The length of a one dimensional array/2 or the number of rows on a two dimensional array will define the number of points.

The polygon is moved into the top left corner of the sprite for you, so it does not matter whereabouts it is drawn — negative coordinates are fine. The sprite is made just big enough to hold the polygon and the penwidth it is drawn with, since half of a line's thickness falls outside the shape it outlines.

One dimensional arrays and lists must have at least six values and an even number of values. A two dimensional array may have 3 or more rows but must have two columns.

Example​

# create an arrow that spins and follows the mouse
spritedim 1
color darkblue, blue
penwidth 2
spritepoly 0, {15,0, 30,10, 25,10, 25,30, 5,30, 5,10, 0,10}

color grey
rect 0,0,300,300
spriteshow 0
s = 1
ds = .1
r = 0
while true
   spriteplace 0, mousex, mousey, s, r
   r = r + .1
   if s > 5 or s < 1 then ds = ds * -1
   s = s + ds
   pause .1
end while
