call motion ?

[1980gamer]

I am trying to place 24 sprite on the screen.

And in a random sequence, have them start moving.

 

My question is... Can you use a variable to start a sprite moving in a call motion?

 

LET #VAR=3

CALL MOTION(#VAR,20,0)

 

I could swear I have done this in the past? Maybe it was in a Sprite command? Though that will not work for me without a rewrite......

 

Hmmm..?

Yes, you can do that. But variables don't start with a '#', only the sprite functions require that.

 

VAR=3

CALL MOTION(#VAR,20,0)

TI (Extended) Basic surely has some syntactic sugar here and there ...

Thanks for verifying it should work.

 

The LET #VAR was a typo... But maybe I had the same typo while testing? #VAR would be a local TEMP TABLE in SQL... So it may have looked correct to me?

 

Sample proof of it working...

1 CALL SCREEN(2)
10 CALL CLEAR
20 RANDOMIZE
30 CALL SPRITE(#1,42,12,120,120)
40 CALL SPRITE(#2,42,13,128,128)
50 CALL SPRITE(#3,42,14,112,112)
60 R=INT(RND*3)+1
70 CALL MOTION(#R,10,10)
80 FOR D=1 TO 500 :: NEXT D
90 CALL MOTION(#R,0,0)
100 GOTO 60
