I need help with my trade system

[Pengaboy]

Hello, i started to create a game.
However i ran into the problems while wanted to add trade system.

How i can add system that indicates following:
when i press update button then it removes 2500 from cash (how to limitate that if my cash is less than 2500 then it just does nothing?)
when i press update button then it raises update price twice (how to indicate how many updates i have done?)
when i press update button then it changes the base image (if i have enough cash for that)?
how to set per update diffirent images while using single update button?

Thanks for help

Do you know about if statements and variables? You can use an if statement and a few variables to do all of that. Here's a small example of an if statement.

Code: Select all

if(cash>=2500)
{
    // this code only runs when you have at least 2500
    // buy whatever item
    cash -= 2500; // removes extra cash
}

cash is variable or actor?

cash is variable or actor?

It is an integer variable. Though you'll need to create it to actually use it.

yeah. its working but i need that it print the value of cash on text actor.
here is the code i use at the moment, i think something wrong with that...

Code: Select all

if(cash >= 2500)
{
    statnumber_cash.textNumber = statnumber_cash.textNumber - 2500;
    cash -= 2500;
}

What is wrong exactly? What should it be doing instead of what it is doing now? That code should only let you decrease cash when it is greater than or equal to 2500, and when you press it it will update the textNumber's value and reduce cash. However if that is what you want it to do, I'd recommend setting it like follows (this way is slightly cleaner).

Code: Select all

if(cash >= 2500)
{
    cash -= 2500;
    statenumber_cash.textNumber = cash;
}

tried that but i didnt work in some odd reason lol, but is there some way to print the value of cash variable instead of single updates so it updates itself automatically.
because that way i keep the code more clear

btw i shall explain about system a bit more though
Actors and Variable im using:
cash(variable/integer/global/array:no/save group:stats
statnumber_cash(text actor for numbers to show cash)
upgrade_button(button for sending commands to actors)

i mean when i click upgrade button then it works like upgrade_button -> cash -> statnumber_cash
and so on
