How to Change a Unit's Move/Regen/Armor (etc...) Type

[SwissDerd]

TO GUI USERS:

• The solutions use the functions And/Or/Xor which can be found in GUI when comparing integers.

Spoiler

• Use the numbers corresponding to certain unit properties (e.g. 2 = MOVE_TYPE_FLY) in your triggers (list is at the bottom of the tutorial)

OR

• (Recommended) Use an integer variable to get the value from their name (list is at the bottom of the tutorial)

PROBLEM: How to check or change certain properties of a unit

Can mix multiple values:

• Movement type (Foot, Fly, etc.) -- Apparently a unit can have any combination of move types... I don't know what the purpose is though
• Targeted as (Ground, Air, Structure, etc.)
• Unit category (Undead, Peon, Ward, Tauren, etc.)
• Pathing prevented by (Unwalkable, Unflyable, etc.)

Can only have one value:

• Armor type (Flesh, Metal, Wood, etc.)
• Defense type (Hero, Fortified, Heavy, etc.)
• Regeneration type (None, Always, Blight, Day, Night)
• Primary hero stat (Strength, Agility, Intelligence)

Spoiler: SOLUTION (JASS):

To CHECK if a unit is classified as "Undead":

if (BlzBitAnd(BlzGetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION), GetHandleId(UNIT_CATEGORY_UNDEAD)) != 0) then
// Unit is undead
else
// Unit is not undead
endif

To ADD the unit category "Undead" to a unit (does nothing if it already has it):

call BlzSetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION, BlzBitOr(BlzGetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION), GetHandleId(UNIT_CATEGORY_UNDEAD)))

To REMOVE the "Undead" category from a unit (does nothing if it already does not have it):

call BlzSetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION, BlzBitAnd(BlzGetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION), -1 - GetHandleId(UNIT_CATEGORY_UNDEAD)))

To TOGGLE the "Undead" category of a unit (switch it to the opposite of its current value):

call BlzSetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION, BlzBitXor(BlzGetUnitIntegerField(myUnit, UNIT_IF_UNIT_CLASSIFICATION), GetHandleId(UNIT_CATEGORY_UNDEAD)))

Spoiler: SOLUTION (GUI):

To CHECK if a unit is classified as "Undead":

To ADD the unit category "Undead" to a unit (does nothing if it already has it):

To REMOVE the "Undead" category from a unit (does nothing if it already does not have it):
Make sure you get the final expression right: -1 - TempInt (negative one minus TempInt)

To TOGGLE the "Undead" category of a unit (switch it to the opposite of its current value):

PROBLEM: How to convert one of these constants into an integer (e.g. MOVE_TYPE_FLY -> 2)

Spoiler: SOLUTION (JASS):

local integer i = GetHandleId(MOVE_TYPE_FLY)

---

PROBLEM: How to convert an integer into one of these constants (e.g. 2 -> MOVE_TYPE_FLY)

Spoiler: SOLUTION (JASS):

local movetype mt = ConvertMoveType(2)

---

PROBLEM: How to use these values with a hashtable

Spoiler: SOLUTION (JASS):

Use the two methods above to store the constant as an integer and then convert it back

For example,

// Save the value
call SaveInteger(myHashtable, parentKey, childKey, GetHandleId(MOVE_TYPE_FLY))
// Load the value
local movetype mt = ConvertMoveType(LoadInteger(myHashtable, parentKey, childKey))

Addendum

Be aware that not all of these operations are guaranteed to work!
In some instances, such as changing a unit's defense type, it may be necessary to reselect the unit to update its UI.

Ehm, I have tried to change the unit field of movement type to fly/amphibious but the unit could not walk on water afterwards. This tutorial only shows how to combine multiple values but not how to make the changes working? The same for primary attributes. I changed the unit field for a hero but it had no effect.
