After asking for so many things and getting so many of my doubts solved, I decided to make a small contribution to the forum myself =P
This system is nearly completed. I don't have a map attachment for it yet, this is just an explanation of what I'm doing in my RPG and how do I do it.
Also feel free to suggest optimization changes and report any leaks/bugs/things that won't work, if they exist.
So, my system has 6 attributes: Attack Power, Defense, Stamina, Spellpower, Knowledge and Resistance.
All my RPG characters are normal units (not heroes), so they don't have the classic attributes (str/agi/int).
-Attack Power:
Kinda self-explanatory... Damage done by the character's normal attacks. This is done by using a Real Variable with array = to the namber of Players the map can support (in my case, 8).
Unfortunatly, there is no way that I know of to convert a variable into the damage property of the unit, so we have to calculate the damage using triggers. We must specify an event for our trigger when a unit takes damage, but there is no such event for generic units. So we must do a small Damage Detection with another trigger. Here is how it works:
Variables:
"Playerchar" = Unit Variable which is set when the player selects his character.
"attackvalue" = Real Variable that represents the Attack Power attribute. You can do whatever you want after you input its value, like multiplying it by 10, or dividing, or even adding one more arithmetic calculation and adding some random values to add to the base damage.
Whenever a character acquires an item or ability that increases his Attack Power, there will be a trigger to "Set attackvalue[number of player]" to add whatever the item/ability gives.
It's recommended to set all damage caused by your characters to 1 in the object editor, so that when they attack they deal only the damage calculated in this trigger.
So, when an unit from Neutral Hostile takes damage, the second trigger will deal additional damage, based on our Attack Power variable, to that unit. Then you ask: "But this way, won't the unit take damage twice?". Well, yes, but that isn't a problem because, in this system, the base damage our characters do is always small, like 1 or 2, remember? So the first damage it takes is irrelevant. It's purpose is only to make the second trigger run.
The condition on the second trigger - (Damage taken) Less than or equal to 5.00 - makes it run only when the damage done comes from our characters, avoiding the trigger to enter an infinite loop.
-Defense
Value subtracted from the damage our characters would receive... Could be a raw value or a percentage. Like the attack power, we can't make the armor property of a unit the value of a variable, so here comes another trigger:
Variables:
Playerchar: We already know this one
defensevalue: Real Variable that represents the amount of damage prevented. Like the attack power, you can do many things with it, like dividing, making it a percentage, etc.
As with the Attack Power system, it's recommended to set the armor of your characters to 0 and make it "unarmored", so that the only damage prevented is the one expected by the defense value.
-Stamina and Knowledge
Those are the coolest attributes of the system. That's because we can actually change the HitPointsMaximum and ManaPointsMaximum of our characters with them. This is done using blade.dk's SetUnitMaxState system. It's a JASS system that uses an Unit Variable and an Integer Variable to set the Unit's max life/mana to the Integer value. So, in this case, we need our stamina and knowledge variables to be Integer variables, not Real variables, like the other ones. We also need a unit variable, but we already have our beloved "Playerchar[nº of owning player]" . Then we just "call" the script, specify our unit and our stamina/knowledge variable, and there it is!
Example:
I may have misswritten some parts of the Custom script, I'm kinda new to JASS, but you get the general idea. The same is done for the knowledge variable. I'll not show another Trigger just for that, because it's pretty simple... Just change the variable from stamina to knowledge, manipulate an item that adds knowledge, and change the "UNIT_STATE_MAX_LIFE" to "UNIT_STATE_MAX_MANA" in the Custom script.
Also, we can make health and mana regeneration based on our stamina/knowledge:
That will "regenerate" our characters life/mana every second, based on their stamina and knowledge divided by, say, 100. Of course, you can divide by whatever value you want. It's up to you to decide how will each Attribute affect the regen.
The "((Real(knowledge[(Player number of (Picked player))])) / 100.00))" part is done by converting an Integer to Real, because, as we know, our stamina and knowledge variables are Integer variables, but for this trigger we need them to be Real variables.
-Spellpower
Spellpower works similarly to the Attack Power... Except we won't calculate the damage when our unit attacks, but when it casts its spells.
Example:
So, basically we use Spellpower in each trigger we do for our custom abilities. Of course, it can be added to the damage of other abilities that are made in the Object Editor in the same way. I don't know if I need to mention: the variable used is "spellpower[nº of player], which is a Real.
-Resistance
It's similar to defense, but used to subtract damage from spells.
Example:
Variable used is "resistancevalue", which is a Real
I just realized there is a small leak in the defense and resistance triggers. I think that by using "Damage taken - defense/resistance", I'm assuming the unit has already taken the damage, so the trigger would only make the unit take that damage again, but now with the reduced value calculated. This can be fixed by adding "Life of unit + Damage taken" and then the rest "- Damage taken". Sounds silly, but would make our unit regain the life it lost and then take the damage we want it to take. There may be a easier method, I'll work on it and keep editing this post.
So, that's it for my Custom Attribute System. Needs a improvement here and there, I think, but may help some people who want to do their own RPGs. Hope you guys like it.
