Items dragging not working as expected

  • #1, by atrusWednesday, 26. April 2017, 11:09 3 years ago
    Hi allo,

    Have the following issue (verified in 4.2.5 and 5rc0):

    I have a use command which works ok with inventory items (USE ... WITH.. ). However when i enable 'Items can be dragged with this command' i can see the cursor changing to the inv item, but when trying to use this item i get a reply from the default comment set. I have also played around with the global option 'Allow dragging items from inventory' but no luck. Maybe i'm missing smth here?

    Thanks!

    Quick note: just woke up, so my head's a bit muggy at the minute.

    dragged items require item dropped actions in scene objects/characters as they have no command attached to them. If you manually create an action inside of an item, say: left click > set command x, set item y then only an action like command x, item y (executed at destination or immediate) would work on scene objects/characters, but if you changed the active command then it would no longer register correctly.

    Personally I'm not a fan of the built in item system; especially the dragged item system. I use a custom command based system for both commands & items because it's much easier to work with & I can use custom mouse cursors which I can assign to each command.

    in the old days of early version 3 you could mix commands and onclick and the inventory worked fine, honestly I can't remember which version it changed.

    I've never tried to achieve the same thing via script, I usually use the onclick and totally ignore the command system

    There's a reason I use commands. If you use a broken sword (single command interface) which a lot of people tend to do these days, then it's likely you have created mouse enters/leaves actions for each of your scene objects/characters which change the mouse cursor. Now, the problem with single command interface & using dragged items is that there's no if query action part to check if you are holding a dragged item (without scripting), & most people probably just add the change cursor action part into the mouse enter/leaves actions which causes the mouse cursor to be forced to whatever is specified, but if a dragged item is in hand the item remains while the cursor is now set to the examine, look, take, etc. cursor.

    I use the broken sword interface myself - I have a single interaction command called "left_click", the rest of the commands I created are for items. On mouse enters/leaves I can query if command is "left_click" change cursor to "examine" end, which prevents cursor from being changed unless my standard command is the current command as all other commands = item. I use the same approach for right click (examine) scene objects/characters too, as I can query if command is "left_click" to perform some character observation actions/display texts otherwise it resets the command to standard command because an item must be in hand.

    The other reason I use commands is because I can assign custom cursors into the properties section of each command which means I don't have to use the over-sized inventory item sprites nor suffer the animation center position (which coincidentally is in the exact center of dragged item cursor sprites rather than the top left).

    Thanks all,

    AFRLme's suggestion works ok and for sure better than the built-in one so we will stick to this.

    As we are using a verb-driven interface we have found the following to work best for mouse enters/leaves (so that your inventory item cursor won't change):

    1. Assign a condition to your character named e.g. 'holding_item' with initial value FALSE.
    2. In your items's actions panel, every time you set the command to use/give this item, make sure you change 'holding_item' to TRUE.
    3. So now, for every mouse enter/leave, make sure you check if your character is holding this item and change the cursors accordingly:

    Cursor enters or leaves object area: if 'holding_item' is false set cursor **your cursor**

    So it will only change cursor if you are not holding an item.

    Important note: make sure you set 'holding_item' back to FALSE when you drop/put the item back to your inventory
