APOLY how to use ?

[hylst]

I'm not sure of my way of using APOLY, used to POLYFILL that is slower.
I've tried :

m&=-1 ! motif
m%=V:m&
DIM xyp(6) ! tableau des coordonnes quel format choisir ? & pour des mots devrait suffire ?!
xyp(0)=319 ! coordonnee d'un triangle x puis y 3 point
xyp(1)=0
xyp(2)=319
xyp(3)=99
xyp(4)=159
xyp(5)=0
pnt%=V:xyp(0)
APOLY pnt%,3,0 TO 199,15,0,m%,0 _ pnt% : pointeurs coord - 3 nbre de points - 0 y min - 199 ymax - 15 couleur - 0 mode affich (rempl) - m% motif (continu) - 0 num de motif

what's wrong with this use of apoly ?

Maybe this example helps:

Code: Tout sélectionner

m&=-1 !solid
m%=V:m&
DIM xyp&(6)
xyp&(0)=319
xyp&(1)=0
xyp&(2)=319
xyp&(3)=99
xyp&(4)=159
xyp&(5)=0
pnt%=V:xyp&(0)
APOLY pnt%,4,0 TO 199,1,0,m%,0


Since the x/y are passed as a pointer, the array must be word type and not float type. The Line-A is expecting word size x/y values and has no idea how to interpret GFA float values.

Hello and thanks again.
I don't undersatnt why, but i used first time word arrays& but it results on nothing, and even sometimes reboot.
I tried again, and then... it worked... i really wonder ... if i don't use narcotics sometimes....
but no... no narcotics, no alcohol, and even no smoking ! I really wonder...

But... why 4 after pnt% ? As there are 3 points and not 4 in the polygon.

I was going by the example in the manual. I'm not exactly sure, does it fail with 3?

[hylst]

Yes.
