Using 1 weapon out of 8

[jweldon]

It's me again, I'm looking for some advice on how to use only 1 weapon of the 8 (at a time) I have in my inventory by only pressing button 1.  Here is what I have so far.

     I have a working inventory screen that allows me to select which ever weapon I want.
          Inventory item: weaponselect (inital value 1, max value (each number = different weapon)
     I have seperate inventory for each weapon, so I can tell if I have found them yet.
          Inventory item: Slingshot (inital value 0, max value 1) (0 = don't have, 1 = have)
          Inventory item: sword 1 (inital value 0, max value 1) (0 = don't have, 1 = have)
          Inventory item: spear (inital value 0, max value 1) (0 = don't have, 1 = have)
          and the list continues through all 8 of my weapons...

I was thinking on the lines of something like this:
Special function 1: If weapon select = 3 activate special function 2.
Special function 2: require spear = 1 (do I own it), activate special function 3
Special function 3: create sprite (spear, basicly fire weapon)

Here is my issue, how do I check to see what weapon has been selected and then only use that weapon and not the weapons with a weapon number less than that number.
    For example weaponselect inventory = 2 (sword1)
    If I create a tile interaction and require weapon select = 2 won't I also get weapons 3-8, because they have atleast 2 in inventory of weaponselect also.  It would activate 7 of my sprites (each weapon)

Is there a way to only require a specific amount in inventory and not a minimum or maximum amount of something in inventory?  If I can understand this, the rest will be easy for me to finish.

Thanks for help with this one.  Sorry if I have confussed you guys, Let me know if I can clear it up...

If you have each inventory item have a maximum of 2 instead of 1, where 0 = Don't have, 1 = Have, 2 = Selected, then have a special function for each weapon where if that weapon's inventory is 2 then use that weapon.  When you select a weapon, simply remove 1 from all weapon inventory items that have 2 (which will always be exactly one) and then add one to the selected weapon.

Huh...Sounds good, how would the Special functions or Tile reactions go for lowering the ones with 2 down to a 1.  Would you use a sequence and always lower the previous weapon before the weapon now selected. Like...

1.Slingshot
2. Sword1
3. Axe
4. Sword 2
5. Boomerang
6. Sword 3
7. Crossbow
8. Mace

Have tiles set to trigger these functions when the cursor moves over the weapon desired.
For example: (to select sword 2)
Special Function 1:Series of Special Functions to include the next 2
Special Function 2: Lower Axe inventory -1
Special Function 3: Riase Sword 2 +1

When I get to #1 have it lower #8 and raise #1

I think I will give this a try,  Thanks for the help.

If you know of anything else let me know.  I was trying to make it alot harder.
How will this work when I have 0 and don't actually have a weapon yet,  I guess it will temperally add it to my inventory, but not allow me to shot it yet.  This might cause someone to cheat in the game.

I'm wondering if I should use 4 numbers instead like this...
0 = Don't have
1 = Still don't have
2 = Have in inventory
3 = Have and selected to use.
When I pick up a weapon I would just add 2 to the inventory instead of one.

Does this sound like it will work,  I'm going to find out and I'll let you know.

Thanks,
John

I don't know how your game works, but here's what I was thinking.  Whenever they press the Attack button, 8 functions activate, each requiring 2 of their specified inventory to actually "attack".  Selecting a weapon would be done by pressing some button combination that activates 8 special functions, each requiring 2 of their specified inventory to subtract 1 from the inventory.
