hello,

I encountered a strange problem in DBP. the problem is the following:
I have an array cards01(60) and all the data in the array is 0.
then I have cards on the screen numbered from 1 to 102. sprite 1001 is the sprite for the mouse. so when I do this:

c=0
for t=1 to 60 step 1
if sprite collision(1001,0)==cards01(t)
c=c+1
endif
next t

so I count how much that card I standing on is in the deck. all the cards should be 0 times in the deck as I did not add any. and for the cards 2 to 102 it is correct. But for the card 1 it is not.

I printed out the values so I could see what was happening and he gave this:

1=0
c=60
?????

so since when is 1=0???? is this a bug in the program are is it something else? I can't see it

Okay,
Personally, I'd remove the == from the equation, but that's just me... = is enough imho.

Now as for the problem, sprite collision (num,0) returns the obejct hit, or ZERO if nothing. If any value in the card01() array is zero, it will be counted as a hit by that code.

Any truly great code should be indisguishable from magic.

ok, thx,

the == was the problem. but I used to write in that way because almost every programming language uses this. = is different from ==.
