Burrow units, please help ...

Hi all,
I'm trying to give the Centaur the Burrow ability and few more creeps I have,
now I'm very good with jass but never mess with the abilities and animation,
so can someone address me what can I do and how should I do it ?

I already try to do it and it didn't went very well I got few problems with it,
I used the Barbed Arachnathid unit and the Burrow (Neutral Hostile) ability

when I'm tryin' to give the Centaur the ability to be burrowed from some reason it do nothing, so what I did I gave the Centaur the model of burrowed Barbed Arachnathid and when I tried to burrow the unit it was burrowed for 1 second and then unborrowed itself, after it he got the Barbed Arachnathid model and had some transparency on the unit,

Now what I want to do is burrow my creeps with their own burrowed model,
so I won't see a different unit after unborrow. is it possible ? if not anyway tell me how to do it the right way from the start please.

Dunno even on what category I should put it :D

Thanks for any help I may get. ;)

you need to create a second unit that is the burrowed unit for that ability, the second unit that is burrowed need a unburrow ability to unborrow back to the tauren.
the ability just switch between the 2 units

My friend is having the same problem.

I have 2 units, 1 for burrow and 1 for normal

When the warden burrows it doesn't do anything, but it can't move due to it being the burrowed version. Now how do I get it to look like it actually burrowed like with crypt fiends, or anything else where you see the patch of ground?

For the burrowed version of your unit, you must use a model that has an alternate "burrowed" animation (crypt fiend, carrion beetles).

A side note: burrowed units shouldn't be able to move, because no model that has an alternate burrow stand animation (like the crypt fiend) has an alternate burrowed walk animation to go with it, so when a burrowed unit tries to walk around, it doesn't use the alternate animation (because it doesn't have it for walking), but uses it's regular walk animation (the unburrowed one).

Hi all, well I figure out my problem, but still I can't have the model looks like the actual creeps unburrowed from the ground, since I use the model of other creep for it, I can understand it but is it possible to actually make my creeps model unborrow from the ground or even burrow ?

Do I need 3D application to make it ? is it complex to do it ?

oh well to see the digs on the ground you need use one of the burrowed model of some creep or unit like you said for example the crypt fiend,
take a close look over does places,

Art - Model File: That should be the model as the normal one.
Art - Special: That should be the model for the Burrow version (copy from crypt fiend).

check out the ability you gave to the warden, go to the abilities tab
take the crypt fiend ability and do copy past so you could have your own custom ability for her,
then make sure you set does places right,

Data - Alternate Form Unit: Choose the burrow version of the warden.
Data - Normal Form Unit: Choose the normal version of the warden.

that should work for you. ;)

I used the model file with a burrowed thing but it also changes the window thing where it shows the face of the unit and that can't happen, unless theres no possible way around it >_>
