I've seen that you guys (AGDI) have add this feature your recent game[s] so I'd like to know how you coded it. If you use the scroll mouse wheel while you have an inventory item selected as your mouse mode, it will go to to the next inventory item automatically...

how did you code this?

BUMP!

I'm certain this much is right...

somewhere in:
function on_mouse_click(...

if (mouse.Mode==eModeUseinv) { //then...
if (button==WHEELNORTH) {
//scroll up;
}
if (button==WHEELSOUTH) {
//scroll down through the inventory...
}
}

So, the part I'm can't figure out is obviously the missing parts. I can't find how to script changing the active inventory item. I'd really appreciate help on filling in the blanks.

p.s. I always return favors when people are nice to me.

I don't often see replies from the AGDI's on the forums so I'm not sure they check them much. You might be better off asking how to do this on the AGS forums.

Yeah, you're probably right.

It's cool though. I figured out how to do it on my own late last night.

Code: Select all

  

else if (mouse.Mode==eModeUseinv) { 
// this bit will allow mousewheel to scroll through inventory if the 
// mouse.Mode is set to use inventory;

int tempInv=character[EGO].ActiveInventory.ID;
int maxInv=25;  

//set maxinv to the maximum inventory items;
    
    if (button==WHEELNORTH) {

      if (tempInv==1)
        tempInv=maxInv;
      else
        tempInv--;
      while(character[EGO].InventoryQuantity[tempInv]==0) { 

//checks to see if the Player has this item

        if (tempInv==1)
          tempInv=maxInv;
        else
          tempInv--;
      }
      character[EGO].ActiveInventory=inventory[tempInv];
    }
    else if (button==WHEELSOUTH) {
      if (tempInv==maxInv)
        tempInv=1;
      else
        tempInv++;
      while(character[EGO].InventoryQuantity[tempInv]==0) { 

//checks to see if the Player has this item

        if (tempInv==maxInv)
          tempInv=1;
        else
          tempInv++;
      }
      character[EGO].ActiveInventory=inventory[tempInv];
    }
  } //end the section for scrolling through inventory
