Make a Slow Tower from Marauder

I am making a really good TD game in SC2 Galaxy Editor. But what's a TD with no slow tower.
I have seen a lot of people using marauders as towers.

So how do i make a slow tower from marauders?
Please give me a step-by-step if possible.

Yes i am familiar with the editor and i have other units (stalker) as a tower that works fine.
My marauder does not shoot, do slow or anything. He just fly on the enemy and disappears.

Your help will be highly appreciated!

ANSWER:
Dublicate marauder. Edit stats. Add ability "build in progress".
Flags make sure it is indestructable.
No movement speed.
You dont have to change begavior and stuff in to structure, it can stay as a unit type.

 

Well, can you get back to the default marauder? All you need to do is make it not able to move, and built like a tower.

 

I would suggest that you change the model file of a tower into a marauder.

 

Model is Tower.
I made a Laser Tower form Stalker. It acts as a unit that can not move, be destroyed. Also it's property is structure, so i was able to do a build time.
Marauders slow ability has to be researched. I thought i had made so there are no requirements and stuff, but it still does not work.

Default marauders when unable to move, suddenly fly on opponent and die.

 

It build correctly. Also does not move. The problem is - it wont shoot at all

 

That's strange. did you make it so that it couldn't turn or anything? Also, you can use triggers to give players upgrades.

 

Didn't know about that. It does turn and it can see the enemy. Just wont shoot.
What info you need to see the mistake?

 

Anything you can tell me about what you edited for the default Marauder, its actor, and the default Marauder weapon.

 

Ok. I deleted the edited marauder. Now Dublicated the original.
under "ACTOR" unit name is marauder.
ACTORS > Marauder
Replaced all the models with the defaults, as it has to be done.
Movement Sped = 0
Everything else under ACTORS is "marauder attack (unnamed) copy"

WEAOPNS:
Weapon target filters: changed ground from required to allows.
Range to 10

Now they shoot but do NOT apply the slow effect. So how do i do that?

 

ok and where do i edit how much the slow effect will apply?

 

Go in to your triggers, search for "upgrade" in the actions, find one that gives upgrades to players.

 

Wha? Whay?

 

So that you can give the Concussive Missiles or whatever upgrade to marauders for all players, then you can edit the slow by changing the behavior this upgrade has in the data module.

 

Ohhh, good one.
BTW, any easy way how to make upgrades for towers. I am doing one but it is painfull. All I want is that after upgrade the stats change and thats it.

 

Do you want the upgrade to be repeatable? Or just once? Because it's easy if you just want it to do it once.

 

Well....
3 times max would be nice.

I am doing it via morph, but something is not right.... there MUST be an easy ways how to upgrade JUST stats.

 

Well, you know the Weapons upgrades from the regular game? You could modify a set of them.

 

I did, but for some reason the upgraded tower stopped shooting. And I cant figure out why.

 

>.< I can't really tell you without knowing the exact changes to the upgrades you made. Perhaps you accidentally removed the link to the weapon from the unit?

 

I'm gonna go back a version and try to do the upgrade thing from scratch. It just would be nice to find a step-by-step tutorial for that upgrade.
