Manipulating number of item uses

9 years ago

Hi there everyone, I have a question. In my story I have a potion which you can use to restore your health, however it has a limited number of uses. I want the character to still have the item in their inventory but be unable to use it once they you have ran out of the number of uses. I also want them to be able to refill the potion, thus resetting the number of uses for the item. Does anyone know if this is possible, and if so, how to do it?

Hi, to do this you need to keep track of uses yourself with a Variable that you create. Then have a page for when the variable uses is zero.

When they refill the potion, reset your variable.

But how could I prevent users from using the item after the amount of uses has expired?

That is what your "This potion is empty" page is for  =)

There's already a system variable for number of uses of an item.

$ITEMUSED1

Each item has a number beside it (which is what the number beside 'used' correlates with). Each time you use the item, the variable gets 1 added to it (so if you used it twice in the game, it would be at 2).

You'd have to use the item script of that item, to do a check when you use it, and if the $ITEMUSED1 value is equal to the limit, change the destination they go to, to some default "there is no more uses".

Unfortunately, there's no "disabling" an item or something.

Of course, when you reach the limit you could always replace the item with an item that looks the same, but has no links to anywhere (and it's description says it can't be used anymore). Then, when they "replenish" the item, switch it back to the old item (and reset $ITEMUSED1 to 0).

That should work!

Displaying a variable in Global Scripts

Displaying Variable in Global Scripts

9 years ago

I have a new problem, In my game I want the player to be able to see the amount of gold they have on every page. But instead of displaying the variable on every page I am using a global script instead. It accepts the script but when I view any of the pages in the story it shows Gold: %%GOLD%% at the bottom of the page.

How can I get it to display Gold: (amount of gold) instead of Gold: %%GOLD%%?

PS: The script I used was this:

$PAGETEXT := $PAGETEXT + "<br><br>"
$PAGETEXT := $PAGETEXT + "<b>Gold:</b> %%GOLD%%"

$PAGETEXT := $PAGETEXT + "<b>Gold: </b>" + %GOLD

Try that.

%GOLD for Scripts and %%GOLD%% for directly on a page in the text.
