Sure. First of all, you need to import the DamageEvent and DamageModifiers libraries into your map. I suggest the Table version of DamageModifiers since Table is slightly easier to import than AutoIndex. Once you have Table, DamageEvent and DamageModifiers in your map (all three are simple copy&paste jobs, just create a trigger, convert it to custom text and overwrite it's contents with the library code), try saving the map. If you have the NewGen editor with the latest JassHelper, this should give you no problems, else you should update your JassHelper. If the map saves successfully then DamageModifiers will automatically generate the bonus life ability it requires to be able to block damage that is higher than a unit's max life. At this point, you should close and reopen the map, then scroll through the DamageModifiers documentation until you find the objectmerger call that generated the aforementioned ability (you can't miss it, it's the only grey-coloured line in the library) and disable it. This will speed up map saves in the future since the editor won't have to generate that ability every time. With that, DamageModifiers should be ready to use. If you want, you can also import one of the preload libraries linked to from the Damage Event thread, but those are completely optional. They're just used to prevent a lag spike that otherwise occurs the first time DamageModifiers needs to use its bonus life ability.  JASS:library AlliedDamageBlocker requires DamageModifiers private struct blocker extends DamageModifier private player owner method onDamageTaken takes unit damageSource, real damage returns real if IsUnitAlly(damageSource, .owner) then return -damage // Block all damage. endif return 0.0 endmethod static method create takes unit u returns blocker local blocker this = blocker.allocate(u, 0) set .owner=GetOwningPlayer(u) return this endmethod endstruct function UnitBlockDamageFromAllies takes unit u returns nothing call blocker.create(u) endfunction /* To use this function in a GUI trigger, copy the following line to a custom script action: call UnitBlockDamageFromAllies( udg_YourUnitVariable ) I didn't include any code that would clean up the damage modifier when the unit dies, but if this is only used on a few units during the course of the game then that's not a problem. */ endlibrary |

This should help you. Zinc://! zinc library PreventAlliedDamage requires DamageEvent, DamageModifiers, AutoIndex { constant integer UNIT_TYPE_ID = 'unit'; /* Change this to the type ID of the unit that you don't want to receive damage. */ constant integer DAMAGE_MODIFIER_PRIORITY = 0x7FFFFFFF; /* Highest possible priority for the damage modifier. */ struct preventIncomingDamage extends DamageModifier { /* This is the filter for the automatic allocation provided by the AutoCreate module. You are free to insert whatever conditions you need here. */ static method createFilter(unit enteringUnit) -> boolean { return (GetUnitTypeId(enteringUnit) == UNIT_TYPE_ID); } /* This method is called whenever the unit for which we created the damage modifier is damaged. */ method onDamageTaken(unit damageSource, real damageAmount) -> real { if (IsUnitAlly(damageSource, GetOwningPlayer(this.me))) { return -damageAmount; /* If the damage source was an ally, then block the whole damage that was dealt. */ } return 0.0; /* Otherwise, return zero in order not to block any damage at all. */ } /* This method will be called by AutoCreate when it tries to automatically create the struct for a certain unit. */ static method create(unit enteringUnit) -> thistype { thistype this = thistype.allocate(enteringUnit, DAMAGE_MODIFIER_PRIORITY); /* Since we are extending the DamageModifier struct, our .allocate() method needs to match the parameters of extended struct's .create() method. */ return this; } /* Implement the AutoCreate and the AutoDestroy modules. */ module AutoCreate; module AutoDestroy; } } //! endzinc EDIT: Okay, Anitarf got to it first. I spent five minutes for nothing. |

You can use a triggered evasion, with the ally condition. Link to my DD system: http://www.wc3c.net/showpost.php?p=1024305&postcount=2 1. Create a trigger, call it "damage detection", set it to custom text, erase the text done by default and replace it with this code:  JASS:2. Create other trigger, put it "AntisplashDamage", and like the first step, erase the ugly code and replace it with this: Block Damage from Allies - requires TimerUtils:3. And that's all :) Edit: Map attached |
