Hello forum,

I want to detect number by number if it's available by decrementing. For example, I have 6 as number and I want to detect step by step in decrementing way, if the number below 6 or 5 or 4 or 3 (and so on), is available. Here is my code. Thank you in advance!

Hello guys, nice to see you both!

I tried both of the commands, doesn't matter where currentweaponslot is, it jumps straight to 6 when initializing the code

In that case , you don't need a for/ next....you had better to put a variable and just trigger the weapon value by distance or by collision....

If gun dist < 10 then weapon=6

It's for selecting a weapon by mouse scroll. Currentweaponslot is the current weapon that is equipped and visible on screen.

Edit: The currentweaponslot must be replaced with any number free downwards, decrementing (if any number is available)

oh I see now the problem is sometimes currentweapon might be 6 and sometimes 1 so the step value would
need to be 1 or maybe -1 so a loop like that cant be used ide use a while loop and precondition it with currentweapon
and when its less than one then make it 6 and if greater than 6 make it one

infact yes, the problem was that I should had not added -1 to step, but just 1...

EDIT: The code is like this now:



Second Edit: Now, if I make a weapon unavailable so, the number 2, let's say, how can I make it skip directly to 1? Got any idea? Thank you so much

Hi Scraggle,

Don't know if the diagram attached helps, so, I will explain: When the user scrolls up and down (mouse scroll wheel), I need to detect incremently and decremently (depending on the scroll if it's up or down), if a variable from 1 to 6 is available to work with. The availabilty of it is determined by an array variable named slotisequipped. If slotisequipped is 0, then the array position let's say, the program picked the number 3... if 3 is unavailable then array[3] is not available so we will move on to 4 or 2. Imagine the weapon scrolling in games.

How's this?
It uses the arrow keys instead of mouse wheel but you can easily change that.


It's a full 'project' to test the code but the bit you've asked for is the SelectWeaponSlot() function

Nice, Scraggle! Thank you!

Just as a learning curve, from what I made there, from my code, is that a legit way to do it, or there is one specific way like yours?

There are always many ways to do everything. If what you have works then it works.

I know this was answered already with excellent code. But as for the question on how else to do this, in maybe a potentially equally or more efficient way... Instead of using a flag to set whether a weapon is available or not, you could also add whatever weapons you've picked up ingame to a dynamic list (an array too, which resizes based on the weapons picked up). Then just use dec or inc to scroll through the temporary list which can only ever have weapons you actually picked up.
