{{Ideas for Stendhal}}

* club/staff

ChadF also suggested another type of weapon skill system that you can review [[Ideas:chad3f|here]]

<br>

<br>

We want to avoid the situation of having to add items to monsters for them in order to combat, so we need to find a way of making compatible both systems ( the above one with the actual ATK/DEF one ).

# Kick idle players<br>No action in X minutes means that you are logged out

==Resting==

(Idea suggested by ''Nirvana'')

It would be nice a player's ''sit'' command to heal. The player sits down, and she heals like 1 point every 10 seconds or something.

===Melee Combat===

# We compute the ''risk'' to hit the target, using their ATK and DEF attributes-

# If risk>0 then we compute if the target blocks the attack, or how much damage the target received.

The formula looks like:

risk_to_hit = 20 * source[ATK] - roll[1D20] * target[DEF]

if risk_to_hit > 0:

max_defence = √(target[DEF] * (10 + target[ARMOR])) * (10 + 0.03 * (target[LEVEL] + 5));

max_attack = source[ATK] * (1 + source[WEAPON])* (1 + 0.03 * (source[LEVEL + 5)) * speed_effect;

where: speed_effect = 1.0 - 0.5 * speed_part * level_part^2;

where: speed_part = 8 / (source[ATTACK_RATE] + 3.0);

level_part = 1.0 - (target[LEVEL] + 5) / (1.2 * (source[LEVEL] + 5));

damage = (8 * max_attack * random[0..1] - max_defence * random[0..1]) / max_defence;

</pre>

There's also small karma effect for both the hitting chance and damage.

See that it is very important the ATK and DEF value, but that you can also get big improvements using weapons, armors, shields, etc...

The benefits you get from your items and skills are directly proportional to your level. The <code>speed_part</code> is responsible for making slow weapons more effective against strong enemies, and fast weapons better against weak enemies.

Creatures are balanced without items, and have constant item DEF of 0 and item ATK 5.

===Range Combat===

Damage from ranged attacks is based on the above formula, but:

* We have a maximum range

* Weapon is most effective on middle range

* Item ATK is the sum of the bow and arrow ATK values

<pre>

ranged_damage = distance_modifier * normal_damage

where:

if range = 0

distance_modifier = 0.8

else

distance_modifier = 4 * (distance / out_of_range - distance^2 / out_of_range^2)

where:

out_of_range = max_range + 1,

Thus <code>ranged_damage</code> reaches the normal maximum damage at middle range, and drops to 0 at maximum range + 1. The point blank case is treated specially to avoid archers being completely helpless at melee.

==Tactics slider==

As a more or less easy to implement feature I (Zuse) suggest tactics sliders. A single (or more) slider(s) which can be adjusted by the player during the game.

For example:

=== Slink---Normal---Run: ===

This slider will allow the players to adjust the speed of movement. With the following consequences;

*Slink: Players are aware of dangerous situations, they will therefore expect to be attacked suddenly (adrenalin-kick ;) ) and they slink to make no noise.

-> +10 %DEF -50% Movement speed, Creatures will start to attack/note players only if there is a very close distance (e.g. 2 tiles) between them.

*Normal: Just normal ;)

*Run: Players like to get fast from A to B (they might like to flee away). The do not take care of noise and surrounding. A attack will surprise them.

-> -10% DEF +50% Movement speed, Creatures will hear the "noisy" player and trying to attack/note the player from much farer (20-30 tiles) distances then normal.

=== Aggress---Normal---Defence: ===

This slider will allow players to adjust whether they like to attack creatures or defences themselves.

*Aggress: The player tries to slaughter the creature as fast as possible, he/she is using fancy hero-tricks, however this open weak points in the defence. Doesn't matter for real a hero which starts to become bloodthirstiness. The little scratches and wounds will be acceptable for a real hero as along as he/she is the winner of this massacre.

-> +15% ATK -15% DEF

*Normal: Again just normal ;)

*Defence: The player is under heavy attack and run out of potion. Help is coming soon from his party. Therefore, it becomes a question of time. "Ditch a hole and stick your head inside" is now the slogan :).

-> -15% ATK +15% DEF

These sliders will make it possible to run different strategies for parties and for longer campaigns. In addition the level of a player is not directly related to the DEF and ATK settings, which make it more interesting because other players do not know about the actual settings. This can help weak players to protect them better and strong players get faster rid of (boring) weak creatures.

==Magic==

{{TODO| update/replace with [[Ideas_for_Stendhal/Magic]] which is the current working document for magic ideas}}

Magic will be mana based, with each spell costing mana.

Also you can have written spells that don't cost mana, but that vanish after they have been used.

We will mainly have 6 elements in Stendhal, maybe 8 later, and those are Fire, Water/Ice, Earth, Wind, Holy and Dark.

The 2 that might be added later is Physical and Mental magic, that focuses on protecting against and strenghtening charm and poison attacks. For now poison will just be treated as a normal attack, and not be affected by any magic resistances.<br>

<br>

For the Element there will be some properties:

* Fire strong vs Water

* Water strong vs Earth

* Earth strong vs Wind

* Wind strong vs Fire

<br>

* Dark strong vs Holy

* Holy strong vs Dark

The Holy and Dark elements will also be used in healings, depending on if the target is a good or an evil creature the dark and holy elements will heal or damage the target.<br>

<br>

Here is some speculative formulas for how magic might be working

<pre>

risk_to_hit = 2 * source[INT] - target[INT] + target[DEF]/2 + roll[1D20] -10

if risk_to_hit > 0:

attacker part = 0,8 * ((roll[1D100]/100) * source[MATK]^2) * (ELEMENT * 0,2) + 4 * source[MATK] * (ELEMENT*0,2)

maxdamage = source[MATK]^2 + 4 * (ELEMENT)

defender_part = 0.6 * (roll[1D100] / 100) * target[DEF]^2 + 2 * target[DEF] * shield + target[DEF] *

armor + 0,5 * target[DEF]* helmet + 0,5* target[DEF] * legs + 0,5 * target[DEF] * boots

damage = ( ( ((attacker_part - defender_part) / maxdamage) * (maxdamage / source[MATK]) ) *

(1 + (target[WEAK] * 0,01)) ) * (1 - target[STRONG] * 0,01)

ELEMENT = The elemental power of the skill that is used (Equivelant to the ATK the equipped weapon has, but for magic).

WEAK = The element that is weak to the skill that is used. (beeing strong in one element makes you weak to another)

STRONG = Is the target strong against the element casted upon him?

</pre>

These Formulas is based on that all creatures have an elemental resistance to all the elements in the game: <br>

* An elemental resistance below 0 means that you gain extra damage from that element -100 means you recive the double damage.

* An elemental resistance of 0 means that there is no change in damage from that element, or the element that is strong against it.<br>

* An elemental resistance of 100 means that the target is immune to that form of damage, but also weak against the element strong against it.<br>

* An elemental resistance of 100+ means that you absorbs some of that element (ie you get healed) having 200 means that instead of getting damaged you get healed the entire damage cast upon you, but you are also very weak against the oposing element.
