Extracted the buy menu of the flagpole to a library, so that other objects can implement a buy menu without having to duplicate the code. An overview of the changes follows:
Library_Base:
- Moved auto-sell functionality to Library_Vendor
- Moved buy and sell functionality to Library_Vendor
- Removed the old engine menu for buying and selling
Library_Vendor:
- Added proplist for accessing local variables, avoiding variable clashes
- Added interfaces GetBuyValue, GetBuyableItems, GetBuyableAmount, ChangeBuyableAmount, GetSellValue
- Changed DoBuy: it uses the interface functions, instead of hardcoded base material
- Changed / merged the existing sell functionality and the flagpole sell functionality in DoSell:
* does not sell items if QueryOnSell returns true
* sell sound only audible to seller
* the sold object tries selling its contents first (for example a bow, if it ever were sellable. This may not hold in the settlement games, but adventures would allow it)
* the sold object ejects any contents before it is removed. These are usually unsellable objects. Previously they would just be removed together with the object. It has to be tested whether this places the items on the ground or at the center of the sold object
* removed the "sell all" functionality on right-click for the moment.
- Still has some functions from the old base selling: CanStack and GetSellableContents, for the auto-sell functionality
- Fixed a logical error in AllowBuyMenuEntries
- Distinguish between buyer/seller and payer more, so that the logic can easily be changed in one line later
- Allow for runtime overloads of interface functions
- Changed inconsistent variable naming to a more consistent one
- Added namespaces to all sounds, the "UnCash" sound still does not exist
- Added localization strings for insufficient wealth
- Fixed property name error (missing 'e')
- Buy menu is active by default
Flagpole:
- Replaced the custom sell functionality (how many of these do we have actually??) with the sell functionality from Library_Vendor
- Buying menu is allowed if the rule is active
System.ocg/Object.c
- global functions Buy and Sell ask the target if it is a vendor, instead of whether it is a base, and do the callback there.
- renamed the argument so that it is no longer called "base", but "vendor"
The player interface is now similar to how picking up works. This should increase acceptance. Also it was pretty fucked up before. The action bar is gone.
The script logic is now outsourced into a new library similar to the other stuff.
Objects can overload the selector for the new interaction (see "call elevator case").
Additional issues hit and resolved when working on this:
Shifting a cursor did not cancel certain actions (and there was no callback for that). This is now solved by adding two new callbacks.
Issues hit and not resolved:
Certain interactions (calling an elevator case, flipping a construction) are in some control library. They should be in the respective objects (and shown via callbacks etc.). Meh.
The internal interface (declaring interactions etc) has a few places where proplists are just translated because the properties are called differently. This is also a fuckup (i.e. a.interaction_object = b.Object) where the properties should just have been called the same in all places from the beginning.
The name "Action Bar" is pretty misleading now as it is no bar. But that's not something visible to the players. todo: cleanup.
..which eliminates the || GetOCF() & OCF_Alive everywhere. It also allows living things to explicitely disable being projectile targets.
This is a lot cleaner imo.
The global System.ocg should not cause any errors even if Objects.ocd is not loaded. This means that any functions that depend on certain definitions (e.g. FindLocation) will just not be available.
This means that you start a roll currently with walking left/right and tapping [down]. OR falling a great height and just holding left/right when landing. When you let go of left/right, you will instantly walk again. This reduces the possibility of the players rolling into an abyss.
Objects now stack iff CanBeStackedWith returns true. The displayed symbol is now the first object of the stack (instead of the definition).
Also fixed barrel to not overwrite the custom name just after setting it.
One of Sven's private functions. I also renamed the control to CON_ModifierMenu1 (from CON_ModifierInventory1), because it's actually supposed to be the menu modifier in general - even if it's mapped on the inventory key.
Or more generally: added support for any modifier key for any other command without the requirement to define a new command based on the old one plus the key. This can be helpful in situations where the player commands are decoupled from the script engine control handling (e.g. with menus).
Currently Shift+Click is only used by the inventory menu to transfer all items of a certain kind.
This better reflects what the function does. "ProjectileHit" was never used solely for projectiles. Neither was everything of that callback ever needed in all places, which resulted in weird flag-parameter hacking and OnStrike-callbacks. Splitting this up also allows customizing different parts of the behavior further (i.e. tumbling) without adding a hundred parameters or flags to the original function.
