2013-08-26Allowed to push attributeinfos for the attribute recalculationErik Schilling4-54/+52
While on it I replaced the id usage in the server with the usage of the AttributeInfo directly. Next steps: - Dehardcode the core attribute ids and store their attributeinfos somewhere in AttributeManager (for now i simply wrapped the ids with getAttributeInfo(). - Move AttributeInfo out of AttributeManager to shorten the usage + to allow using a pointer in ModifierLocation without forward declaring it.
2013-08-26Removed ability categoriesErik Schilling2-3/+3
2013-08-26Made cooldowns of abilities scriptableErik Schilling2-0/+2
- Removed hardcoded using of attributes - Simply introduced lua functions to set global and ability cooldowns - Requires database update - Bumps the protocol
2013-08-26Readded level handlingErik Schilling5-4/+123
Things done: Wrote a entity:give_experience function (lua side only). Renamed characterpoints to attributepoints (no db update. Did not want to do one for a simple rename). Temponary introduced a ATTR_LEVEL constant. TODO: dehardcode this. Script binds for settings the correction and attribute points.
2013-08-26Readded Entity:damage as lua functionErik Schilling5-15/+44
2013-08-26Added a first very basic monster ai versionErik Schilling4-38/+167
The ai is similar to the old c++ version. Only the target searching is executed every 10 ticks only now to prevent performance issues with too many lua calls.
2013-08-26[Abilities] Added abilities to monstersErik Schilling1-0/+97
Monsters can now either receive abilities at lifetime via scripts, or via the <ability> node in the monsters node.
2013-08-26[Abilities] Removed the old autoattack systemErik Schilling2-16/+0
As a side effect i had to remove the monster attack AI for now. I will readd this as next thing.
2013-08-26[Abilities] Added a add_hit_taken bindErik Schilling1-0/+4
This allows to display hit messages in the client for abilities
2013-08-26[Abilities] Made a first example attack abilityErik Schilling1-2/+20
2013-08-26[Abilities] Added support for a global cooldownErik Schilling1-1/+4
Each ability can now define a cooldown that prevents the player from using other abilities for a while. The time of this cooldown can be set to any attribute. The modified value of the attribute is the value of the cooldown in game ticks. The cooldown will be automatically started if the ability has `autoconsume` set to true. Otherwise a script has to call entity:cooldown_ability(ability).
2013-08-26[Abilities] Added a autoconsume optionErik Schilling1-1/+0
You do not need to reset the mana in the scripts if you do not want to. We will need this for attacks later since those do not nessecary have a script.
2013-08-26[Abilities] Removed all except one abilityErik Schilling1-5/+0
Should allow easier modification without thinking of useful examples for each one
2013-08-26[Abilities] Turned special 1 into a point target for easier testingErik Schilling1-1/+1
2013-08-26[Abilities] Renamed specials to abilitiesErik Schilling2-8/+8
2013-05-03Made member function tables available as a globalsThorbjørn Lindeijer3-11/+11
This way the scripts can add or replace existing member functions, which can be useful. As demonstration chr_money and chr_money_change are now added as Entity.money and Entity.change_money. Also fixed the banker to use ask_number instead of ask_integer (I had decided to rename this and apparently forgot the banker). Mantis-issue: 503 Reviewed-by: Ablu

2013-04-14Simplified some script function namesThorbjørn Lindeijer8-73/+71
npc_message -> say npc_choice -> ask npc_ask_integer -> ask_number npc_ask_string -> ask_string npc_trade -> trade
2013-04-14Removed NPC and character parameters from NPC functionsThorbjørn Lindeijer8-75/+72
These functions can only be used in the context of a character talking to an NPC, so these parameters can be deduced from that context rather than passing them explicitly all the time. Simplifies NPC scripting.
2013-04-14Use a full user data for Entity referencesThorbjørn Lindeijer1-1/+1
Only moved a single script function to a member for now, will do others in a separate commit.
2013-02-21Removed loading of script files using the statusmanagerErik Schilling2-0/+4
They are now required via the main.lua. Also made Harmony giving you the plague in order to allow testing.
2013-02-16Fixed last second reordering of function parameters in last commitErik Schilling1-5/+5
Accidently only reordered the order in the definition but not in the calls
2013-02-04Moved attribute (re)calculation to the scriptsErik Schilling2-0/+75
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.
2013-01-08Added script binds for getting attack informationErik Schilling1-1/+4
New binds: - Damage: - id - skill - base - delta - cth - element - type - truestrike - range - Attack: - priority - cooldown - warmup - global_cooldown - damage - on_attack - MonsterClass: - attacks - ItemClass: - attacks
2012-04-04Enhanced special supportErik Schilling1-23/+10
- 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.

2012-03-11Register Lua script API functions into the global namespaceThorbjørn Lindeijer16-196/+196
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 Lindeijer1-7/+7
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 Lindeijer1-2/+0
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.

2012-03-03Made some global Lua variables localThorbjørn Lindeijer2-47/+46
We have to be careful with introducing globals now that there is only a single Lua state, so we shouldn't use globals unnecessarily. Any variable should be declared 'local' unless there is a reason to make it global. For additional safety we can also think about disallowing the use of globals entirely. This also helps to catch typos in scripts. Reviewed-by: Erik Schilling
2012-03-03Use callbacks for items, monsters and status effectsThorbjørn Lindeijer5-7/+20
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 Lindeijer1-4/+4
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 Lindeijer1-6/+11
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 Lindeijer4-5/+5
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.

2012-02-25Merged the example client and server dataThorbjørn Lindeijer18-0/+1089
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
