2012-03-02Use callbacks for handling character death and respawnThorbjørn Lindeijer1-0/+26
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.

2012-02-03Added a generic Lua user data cacheThorbjørn Lindeijer1-2/+2
Based on a native Lua table with weak values, so that the user data objects that are created can be garbage collected when no longer referenced. Reviewed-by: Yohann Ferreira
2012-01-31Use a full user data object for MapObject referencesThorbjørn Lindeijer1-46/+20
Based on a templated helper class, MapObject references in Lua scripts are now full user data objects. Using the '__index' member of their metatable, a library is associated with it so that member functions can be called directly on the object. Reviewed-by: Yohann Ferreira Reviewed-by: Erik Schilling
2012-01-30Fixed some lua_newtable/createtable usageThorbjørn Lindeijer1-2/+2
When creating a Lua table, it is possible to specify in advance how many array elements and how many non-array elements this table will contain, to avoid dynamic reallocations while filling the table. This wasn't used optimally by the pushSTLContainer helper methods and some other cases. Reviewed-by: Erik Schilling Reviewed-by: Yohann Ferreira

2011-09-28Made the npc_create() function use insertion enqueueing.Yohann Ferreira1-4/+1
As the server was exitting when the insertion was failing anyway, and because the GameState::update() doesn't allow actor insertion while the update process, it was then pretty weird to not use an enqueued insertion for it. Plus, it fixes an assertion failure when scheduling an npc creation. Resolves: Mana-Mantis #360. Reviewed-by: o11c.

A race condition on the being pointer could happen when the being queue was highly requested. IMHO, using queues to add being but remove them directly is the way to go. Resolves: Mana-Mantis #384

2011-07-27Removed the inventory delay mode for now.Yohann Ferreira1-4/+5
I said I wouldn't do it, but I change my mind. Here is why: The delay mode is used in the trading code, and in the inventory code for lua only. In the lua part, the delay mode is useless as it is used only when the script is requesting removal of more items than owned. This is something that can't be handled well anyway, as for the script part, even when the character was still keeping its items. Plus, it's not actually an error, IMHO. In the trading code, it made sense. But the next commit will bring design changes making the inventory items and the equipment items not linked anymore. Hence, making it impossible to trade equipped items, for instance, which is a good thing IMHO. It will also remove the need of a delayed inventory mode in that case. The two cases where it is used will disappear, making it useless. Last but no least, the part watching for equipment changes in the commit() function is not something easy to debug without first having a proper and working base. (checking of two multimaps changes, for instance). We can add it back once the code has been fully debugged for the most skilled among us. And yes, I am sure of what I'm currently doing. For now the whole inventory and trading code is in need of review but it already was, anyway.

2011-03-18Improved error handling in chr_shake_screen Lua functionThorbjørn Lindeijer1-22/+10
It's better to use luaL_checkint than manually checking and printing out an error, since using the helper function makes a more informative error message. Also, scripts errors need to be raised before constructing objects, since due to the way Lua does error handling the destructors of the objects will not be called. Also fixed an issue with the 4th parameter, which was first cast to integer and then multiplied by 10000. Now the multiplication happens before the casting to integer. Reviewed-by: Crush
