2013-04-02Moved fighting code into a componentErik Schilling1-2/+3
All damage dealing is now handeled via CombatComponent. Monsters use a derived MonsterCombatComponent since they can have a damage mutation and have a seperate script callback. The wirering with Being is still not optional since most of the stuff does not exist as components. Things done: - Seperated the fighting code from Being and only let Characters and Monsters add the Component (less overhead for npcs) - Added a getter for Attribute values to prevent searching it all the time in non Being members - Fixed the type if the damage mutation to double (no idea why it was int) I did not want to copy it over incorrectly - Removed the addAttack/removeAttack overrides in Character and made the knuckleAttack being added based on newly added signals Future TODOS: - Remove depedency on Being as soon all needed dependencies are available as components of Entity - Move the monster script callback into the general combatcomponent and make it usuable for characters too

2013-03-25Changed Item to a component of ActorThorbjørn Lindeijer1-9/+5
Items also have positions, so the ItemComponent only makes sense as part of an Actor. Later on it will probably be part of an entity that also has an ActorComponent. Since it was annoying to update all the places where items were created, I've introduced a function for this. The component types are now prefixed with "CT_" because I wanted to introduce an 'Item' namespace which would otherwise be conflicting. The component types enum isn't used much in the code so it can look a bit ugly. Reviewed-by: Yohann Ferreira

2013-02-24Documented all lua binds directly in the sourceErik Schilling1-1341/+2201
This change adds a comment to each lua binding. In the future a script should parse those and generate the docs from them. This should prevent outdated docs and duplicate effort to keep code and docs synced. In C++ categories can be defined in this way: /** LUA_CATEGORY long description of the category (shortname) * further text * goes into * the next lines */ The shortname is only used to bind other comments to the category. In lua the category would look like this: --- LUA_CATEGORY long description of the category (shortname) -- further text -- goes into -- the next lines A comment that describes a bind then can look like this: /** LUA some_function (shortnameofcategory) * some_function(string name) * some_function(int id) ** * Description */ Or in Lua: --- LUA some_function (shortnameofcategory) -- some_function(string name) -- some_function(int id) --- -- Description Autoupdates script follows soon
2013-02-21Introduced Script::ContextErik Schilling1-8/+2
This should allow to finally call functions to lua without having to care about working around situations where a lua call causes a c++ call which needs to call to lua again. Tested against the source of tales repository data.
2013-02-04Moved attribute (re)calculation to the scriptsErik Schilling1-0/+26
This introduces two callbacks: - on_update_derived_attribute -> Called to recalculate other derived attributes. - on_recalculate_base_attribute -> Called to recalculate a base attribute (only called for characters. However the function passed as callback can be useful for recalculating the derived attributes as well) Monsters no longer block recalculation of attributes except HP and Speed. I saw no sense to keep this. Fixed constant value in libmana-constants.lua Dropped bool type of the recalculation functions. It would be difficult to keep it while pushing all to the script engine and it was unused anyway. All in all this adds a LOT more flexibillity to projects since they can now adapt all attributes in the way they want.
2013-01-09Replaced EventListener with signals based on libsigc++Thorbjørn Lindeijer1-1/+5
This replaces the rather hard to understand event dispatcher with a probably even harder to understand templated library, but fortunately we can rely on the available documentation. Hopefully it will also help with the readability of our code and with adding additional signals to other classes. Added libsigc++ to README and Travis CI configuration. Reviewed-by: Erik Schilling
2013-01-09Micro-optimizations for pushing strings to LuaThorbjørn Lindeijer1-32/+24
Use lua_pushliteral and lua_pushlstring instead of lua_pushstring, which avoids Lua having to determine the length of the string.

- Made the current charge being saved. - Added script binds: - chr_set_special_recharge_speed - chr_get_special_recharge_speed - chr_set_special_mana - chr_get_special_mana - get_special_info - Added special info lua class. Functions: - name - needed_mana - rechargeable - on_use - on_recharged - category Further the engine no longer sets charge to 0 after using of specials this allows more flexbilillity (like failing specials). Changes on the xml database: - recharge renamed to rechargeable (needed by client and server) - needed - the needed mana to trigger a special (server only) - rechargespeed - the defailt recharge speed in mana per tick (server only) - target - the type of target (either being or point) (server and client) I also made the lua engine pushing nil instead of a 0 light userdata when the pointer was 0. Database update needed. Change is tested. Mana-Mantis: #167, #156 Reviewed-by: bjorn.

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 Lindeijer1-82/+55
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.

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

This allows the script to let the character perform a scripted attack but the character still gets xp and killed monsters give drops.

2012-03-05Improved Lua API argument checkingThorbjørn Lindeijer1-572/+159
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
2012-03-03Removed the last direct call to global script functionThorbjørn Lindeijer1-12/+15
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 Lindeijer1-152/+29
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 Lindeijer1-30/+81
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
