Using CALL SPRITE over 1000 times faster than FOR loops

a while ago I just thought 'huh, why is the raycaster calc84 so fast?' Since I am no computer science genius, I decided to test it using the scientific method, using code similiar to this:

DEF WP SP,X,Y,Z'weak perspective(basically perspective minus camera rotation)
 VAR X%,Y%
 IF Z == 0 THEN X% = 200:Y% = 120:SCL = 1 ELSE SCL = 1/Z
 X% = (X/Z) + 200
 Y% = 120 - (Y/Z)
 SPSCALE SP,SCL,SCL
 SPOFS SP,X%,Y%
END

DEF WP2
 VAR X%,Y%
 IF SPVAR(CALLIDX,2) == 0 THEN X% = 200:Y% = 120:SCL = 1 ELSE SCL = 1/Z
 X% = (SPVAR(CALLIDX,0)/SPVAR(CALLIDX,2)) + 200
 Y% = 120 - (SPVAR(CALLIDX,1)/SPVAR(CALLIDX,2))
 SPSCALE CALLIDX,SCL,SCL
 SPOFS CALLIDX,X%,Y%
END
'----initialize----
VAR X = RND(100),Y=RND(100),Z=RND(10)
FOR I = 0 TO 511
 SPSET I,0
 SPVAR I,0,X
 SPVAR I,1,Y
 SPVAR I,2,Z
 SPFUNC I,WP2
NEXT
'now the testing begins:
M% = MILLISEC
FOR I = 0 TO 511
 WP I,X,Y,Z
NEXT
FORTIME% = MILLISEC-M%
M% = MILLISEC
CALL SPRITE
CALLSPTIME% = MILLISEC - M%

okay

results?

i demand evidence

I will post them @fter school. I can be on my computer rn, but not my 3DS.(results will be on N3DS XL)

I didn't know the school days in the US mean 3 days :P Jokes aside, I'm interested in proof of this.

you can prove it by independent verification, but that assumes that the procedure is correct

i forgot.

it will be forgotten forever

It will be remembered at 10:0shovel.

Now I look STUPID because it is actually slower lol

I don't know HOW i got 1000 times faster. For some reason, when I put SPSET SP,0 in WP, WP2 is a LOT faster. I think it's because it resets the SPVARS on the sprites...

that makes sense lol

this is the part where the teacher hands your assignment back with question marks and "incomplete? see me after class" written on it

lol ikr
