Math problem with boolean

gamevicci

Hi guys, here's the problem:

I have 10 boolean attribute and 1 integer attribute
I want that the integer attribute is boolean1+boolean2+boolean3 etc, but It doesn't work

for example: If I change the integer attribute to boolean1, the integer become 1
but If I change the integer attribute to boolean1+boolean2, the integer become 0 (even if boolean1 is true and boolean2 is false).

Is it possible to make an addition of boolean attributes?
Thanks !

Never tried to add booleans before.

Could you just use intergers in place of the booleans, having 0 in place as false, and 1 in place of true?

Then you can add those together no problem

John's system does work but it seems a little strange that booleans can be written as 0 or 1 (as well as false/true) and not be read as that. If you don't want to change your booleans to integers you could use a rule for each boolean that adds or subtracts from an integer based on true or false (1/0).

Hi Jonh! Thanks for answering
I have 94 attribute, so 94 integer are too heavy for the memory on my 3gs

old_kipper's solution is what I was thinking to use.

Is it possible that in previous GS version the addition of boolean worked well?

My guess would be that it lets you use 0,1 to set true or false in a boolean, but doesnt actually hold the value of 0 and 1. In the value theres no place to put a number, only the check box to indicate true of false. So thats only a way to change the states, and they dont actually have that value held in them. Just like if you display a boolean in a display textm it displays true or false because thats the actual value its holding, not 0/1.

Ive also never noticed a differnce in memeroy by using differnt attributes types.I have a couple projects i started a while ago that have 500+ interger attributes that run fine.

So i bet your gonna have to change them, you can use index if theres no negative numbers, which take up less memory per say.

cheers

Thanks John I will try!
