[FILLED] A Tax Script

[Mega Flare]

Okay I think this would be simple. I want a script so I can add Tax to items i buy. So before you decide what you want to buy you use script command thing to tell what the tax rate is. Like if its 4% and you buy a potion thats 50Coins it will cost you 52coins. Also I would like it to tell you what the tax rate in the shop

 

[Mega Flare]

im going to BUMP this right now

 

[The_Falcon]

I'm working on this, It's almost done.

Too tired, Ill finish this tommrow, I just need to fix a bug, Ruby isnt handeling decimals.

 

[Mega Flare]

Oh someone is working on it YAY. The decimals dont really need to be there

 

[The_Falcon]

No, I need to convert a variable in to a decimal, and it isn't working right -_-
When I find out how to round up, this will be done quickly

 

[SephirothSpawn]

make sure you are using floats, not fixnums. By default, 50 * (5 / 100) is actually 50 * 0 = 0 because it rounds the 5 / 100 to 0.

Make sure you are using something like

price = Integer(orginal_price * ( (100 + tax) / 100.0 ))

 

[The_Falcon]

THANK YOU!!!!!
I knew how to do this in C++....:P I just needed the float and interger snythaxs :P

 

[The_Falcon]

It's done, paste this somewhere above main, below everything else:

It uses the 1st variable to use taxes, you need to change that before each shop is called. You can also change the variable used by changing all lines which say $game_variables[1] to $game_variables[VARIABLE GO HERE!!!]

Tell me if you want anything else added or you get a bug

 

[Mega Flare]

IT WORKS! IT WORKS! Thank you so much! I got one question. With using varibles I can't use decimals right? It doesnt matter if I can't. And Thank you so much! You should post this in the Submited scripts

 

[The_Falcon]

Yeah, you cant use decimals. If you want though, I'll make it so the tax can handle decimals.

I'll post this in Submitted Scripts shortly

 

[Mega Flare]

I don't need it to handle Decimals. But I like this script. Its so awesome

 

[The_Falcon]

Glad you like it
I posted it in the Scripts section.

 

[RMXPirate]

It would be cooler if you could use it with attibutes instead if you put a attribute called 2 for example it adds 2 dollars tax on it. The maximumm is 7 dollars tax get it so 7 attributes numbered 1-7 and each one means different amount of tax. IT would be so much easier.

 

[Exsharaen]

Wait... can I define different taxes for different shops? For example, let's say shop A have tax 5%. Shop B will have tax 7%, and maybe shop C will have only 2%. It would be nice if you can do this with this script.

 

[Mega Flare]

well first of all you should post in the topic. http://www.rmxp.org/forums/showthread.php?t=6051 and 2nd yes you can. Theres a diffrent version out. It makes it easyer to do that.
