2012-03-11Register Lua script API functions into the global namespaceThorbjørn Lindeijer1-2/+3
Scripts mostly execute the Mana script API, and it seems like just unnecessary verbosity to refer to the 'mana' table all the time. This table no longer exists now. Reviewed-by: Erik Schilling
2012-03-11Removed the create_npc wrapper and the last two NPC callbacksThorbjørn Lindeijer11-72/+156
When creating an NPC, you now provide its optional talk and update functions directly rather than them being stored in a table on the Lua side and then called in response to a global callback. Also fixed an issue with a missing gender parameter to the delayed NPC creation callback used by NPCs defined on the map (found by Erik while reviewing this patch). Reviewed-by: Erik Schilling

2012-03-10Moved the managing of NPC script coroutines into C++Thorbjørn Lindeijer15-222/+443
Rather than wrapping NPC functions up in coroutines in the Lua side, they are now managed on the C++ side as "script threads", which are essentially the same thing. The main purpose is that the server can now know whether any of these long running script interactions are still active, which will probably be useful when adding the ability to reload scripts.

2012-03-07Added a function that returns the current map or raises an errorThorbjørn Lindeijer5-136/+80
The new function 'checkCurrentMap' will raise an error when no current map has been set, eliminating the need to do custom error handling all over the place. This also fixes several functions that would otherwise have simply crashed when there was no current map. Also cleaned up some "empty string parameter" checks. Reviewed-by: Erik Schilling

2012-03-05Added lua function for getting pvp status of mapErik Schilling2-2/+15
mana.map_get_pvp() now returns one of the constants in libmana-constants.lua Reviewed-by: Bertram.
2012-03-05Added possibility to make a being attack an other beingErik Schilling4-35/+61
This allows the script to let the character perform a scripted attack but the character still gets xp and killed monsters give drops. You can now call: mana.being_damage(target, dmg, dmg_delta, accurancy, type, element, source, skill) While on it I also added checks to the being_damage function. Reviewed-by: bjorn, Bertram.
2012-03-05Improved Lua API argument checkingThorbjørn Lindeijer3-580/+194
It's a bit embarrassing the way this has gotten out of hand. The error checking was inconsistent, and in some cases wrong. A host of new helper functions, starting with 'check' rather than 'get', perform error handling on function arguments (they will not return when encountering an error). Reviewed-by: Erik Schilling
2012-03-04SQLite: Added a timeout for trying to acquire a database lockThorbjørn Lindeijer1-0/+4
Without a timeout, trying to write to a locked database fails immediately. Now it will only fail when it can't retrieve a write lock within a second. Still, we need to go through all the SQLite code some time, since there is a lot of error handling missing. We also need to make sure that errors are handled correctly on the higher level. Reviewed-by: Yohann Ferreira
2012-03-03Removed the last direct call to global script functionThorbjørn Lindeijer6-39/+30
The ScriptAction of the TriggerArea (which can be created by mana.trigger_create) was still using a named global function for its callback. Now it also uses a reference to a script function. Since it was the last occurrence of a call to a global script function, I've also removed the Script::prepare(std::string) overload. Reviewed-by: Erik Schilling Mantis-issue: 299
2012-03-03Improved handling of item and monster class parametersThorbjørn Lindeijer3-163/+108
Item and monster classes could already be identified by either their id or their name. Now the explicit values returned by 'get_item_class' and 'get_monster_class' can also be used as parameter. In addition the above two getters learned to understand all three types of parameter as well, rather than only supporting a name. Reviewed-by: Erik Schilling
2012-03-03Use callbacks for items, monsters and status effectsThorbjørn Lindeijer13-127/+241
Previously, global function names were defined in the respective XML definitions of items, monsters and status effects. This was reasonable when they all had the same state, but now they're sharing the single global Lua state. Now the Lua API provides access to the ItemClass, MonsterClass and StatusEffect instances, on which callbacks for both standard and custom events can be explicitly set. Reviewed-by: Erik Schilling

2012-03-02Converted functions called by LuaScript to callbacksThorbjørn Lindeijer9-55/+119
This includes the quest reply, post reply, death notification and remove notification. Also, Script::Ref was changed from a typedef to a small class, automating initialization and making the check for validness clearer. Reviewed-by: Erik Schilling
2012-03-02Use callbacks for handling character death and respawnThorbjørn Lindeijer9-27/+114
Rather than relying on the availability of global functions with certain predefined names, the Lua script now calls API functions to set which function should be called on these global events. This mechanism should make it easier to avoid name collisions in the global namespace, which is important now that there is only a single script state. For these global events this was not likely to become a problem, but this solution can also be used for callbacks on specific item or monster types, or even allow setting callbacks on certain instances.

2012-03-02Merged all the different Lua states into oneThorbjørn Lindeijer19-267/+259
No more Lua state for each status effect, monster, item effect or map. All scripts are loaded into the same state. This should be more efficient overall and make it easier to implement dynamic reloading of the scripts in the future. Now, this introduces the problem of name collisions between different Lua scripts. For now this is solved by using more specific function names, like 'tick_plague' and 'tick_jump' rather than just 'tick'. The plan is however to get rid of these globals, and register these callbacks from the script, so that they can be local functions without the danger of colliding with other scripts.

It's easier to just talk about world data and to modify it as a whole. If there is really a need to separate it, a project can still choose to do that (and in whatever suitable way). There is no need to enforce this separation or to do it in our example. Reviewed-by: Erik Schilling
