hi ummmmmmmmmmm can ne one tell me what a module is? i dont know and could u give me an example of one, thanks
ok now i need help with some mathimatical crap ok so... i am learning how to do basics for rpg and crap like the attack and defense... i ran into a problem... i did the the attack / defense and multiplied it by 3 so the dmg wouldnt be so low... i got
attack = 50
defense = 100
multiple = 3
dmg = (attack / defense) * multiple
print "damage = "; dmg

and it came out as 0 when it should of did something like 1.5 and rounded it up two... please help i was thinking this might have to do with the real data type instead of just integer...

You're right it is to do with the real data type.
Because all your variables are integers it won't work
eg. 50/100 = 0.5 put this into an integer variable and you get 0
multiply that by anything at all and you get 0

You need to put a # symbol at the end of each variable name to assign it as a real number.

attack# = 50
defense# = 100
mutliple# = 3
dmg#= (attack#/defense#)*multiple#
print "damage = ";dmg#

This will give you 1.5

Nine lives to choose from and I get stuck with this one!

I think he was expecting the compiler to round his number up to the nearest integral value like vb6 does. I didnt know that dbpro didnt do this

Isn't there a space and speed advantage in keeping to interger variables? So wouldn't manipulating the equation work better. I only got DBpro last week and have been having this problem.

dmg = ((attack*1.0) / defense) * multiple

This works OK. the *1.0 gives a real result.

Or is all this a waste of time. I run intelligent A-Life communities with around 100,000 members so I need all the speed and compacting I can get.
