Lua Dodge system for TFS 1.3

[Icaraii]

Hello guys,

Can anyone make a dodge system with this things:

• Dodge means miss damage
• Dodge will work with % of happening or not
• The chance for the dodge happening will vary from item to item and not every item will have a % of dodge, that means the script need to be structured in a way that it's something like this:

Item id = 1111 = 30% chance of dodge happen
item id = 2222 = 5% chance of dodge happen
That means that all itens id 1111 will have a chance of 30% of dodge happening when they are equipped.

It can be lua or revscript.

I did found a lot of dodge system, but they did not miss damage, they just reduce the amount of damage the player received. Also I found dodge systems that the player needed to use a stone at the item to apply dodge by lvl, varing from 1 to 100 and those dodge systems ain't what I need.

No, it shouldn't be. It's a single storage value that holds your dodge chance %.

Also I got this error on TFS:

Edited my post above, to fix this.

@Xikini

just tested your script out

as soon as you use helmet and put it away
you keep the dodge system
idk what about other item parts

seems like you are not using classicEquipmentSlots = false so changing an item from a slot to another is still considered by the engine as OnEquip

changed to false
still same

 

[Icaraii]

Listen, I test the problem and it happens in my server when:

Player has full dodge set and log out, then log in and immediately take of the set, then player has dodge without set until he dies or relog

 

[Icaraii]

Guys, I found a problem, when another player uses exura sio into someone that is using a set with dodge, it has a chance to miss the heal, how can we fix it?

 

[Icaraii]

@Xikini, could you take a look at a problem in this script? When the player that has dodge chance heal himself, or get healed by someone else, it also get dodged. Is there a way to fix it? The dodge can happen when player heal with spell and potion aswel.

 

[zbizu]

if primaryType == COMBAT_HEALING then
    return primaryDamage, primaryType, secondaryDamage, secondaryType
end

Use @zbizu's code for the healthChange
Use the code below for the manaChange

    if primaryType == COMBAT_MANADRAIN and primaryDamage > 0 then
        return primaryDamage, primaryType, secondaryDamage, secondaryType
    end

 

[Icaraii]

It works guys, thanks
