I wrote this guide to help people add a rather simple floating item. This code is written, tested, and works on stock tbaMUD 3.61. It may or may not work if your game is heavily modified or from an older version of CWG.
To use a floating item, the player must <b>release (keyword)</b>. It will only work on an item that is set to be a FLOATING wear item.
Code:
// In act.item.c> in wear_bitvectors, add it to the end of the list. ***
// Note: Don't forget to add a comma after the last one! (And don't put one after your new addition...) ***
int wear_bitvectors[] = {
ITEM_WEAR_TAKE, ITEM_WEAR_FINGER, ITEM_WEAR_FINGER, ITEM_WEAR_NECK,
ITEM_WEAR_NECK, ITEM_WEAR_BODY, ITEM_WEAR_HEAD, ITEM_WEAR_LEGS,
ITEM_WEAR_FEET, ITEM_WEAR_HANDS, ITEM_WEAR_ARMS, ITEM_WEAR_SHIELD,
ITEM_WEAR_ABOUT, ITEM_WEAR_WAIST, ITEM_WEAR_WRIST, ITEM_WEAR_WRIST,
- ITEM_WEAR_WIELD, ITEM_WEAR_TAKE, ITEM_WEAR_ANKLE, ITEM_WEAR_ANKLE
+ ITEM_WEAR_WIELD, ITEM_WEAR_TAKE, ITEM_WEAR_ANKLE, ITEM_WEAR_ANKLE,
+ ITEM_WEAR_FLOATING
};
// In const char *already_wearing, add it to the bottom. Don't forget to pay attention to the commas! ***
"You're already wearing something around both of your wrists.\r\n",
"You're already wielding a weapon.\r\n",
- "You're already holding something.\r\n"
+ "You're already holding something.\r\n",
+ "You're already using something as a floaty.\r\n"
};
// In *keywords, add it to the bottom. There must be a comma at the end of the last line! ***
"hands",
"arms",
"shield",
"about",
"waist",
"wrist",

else {
if (!CAN_WEAR(obj, ITEM_WEAR_FLOATING))
send_to_char(ch, "You can't release that as a floaty.\r\n");

Not hard at all. Please feel free to comment with suggestions for additions, or point out if I've missed anything.
