quick question

Hmm i was wondering if you could get a trigger and get it to do math functions and then send the answer back to the game, so you would say what the answer was

you could easily do that

well say the trigger was to match on like

so and so says,"i have 50 cows, and i gave you 30, divide by 2." (numbers are different so)

and i needed to do the math, how would i set that up?

For that exact say ("i have 50 cows, and i gave you 30, divide by 2.") you'd need the following trigger, granted that you need to divide the remainder of subtracting 20 from 50 by 2 (50-20)/2:

match = "i have * cows, and i gave you *, divide by *."
send = "world.note cstr((%1 - %2)/%3)
send to = Scripting

you need to have scripting enabled and vbscript as your scripting language for that to work.

ok another question with math functions!

so and so transferrers * credits to you. (trigger)

what i want it to do is add the * to a variable so say its 10 and the variable was 1, to change it to 11

You need to convert the variable to an integer.

Thus you might do this:

Match: * transfers * credits to you.
Send: SetVariable "credits", CInt (GetVariable ("credits")) + %2
Send to: script

say you have a trigger to change colour of the person transferring you the credits, would that affect the trigger?

Yes, probably I would have it a lower sequence number (eg. 90), a regular expression, so it affects the name only, and check the "keep evaluating" box so that the other trigger also fires.
