I have a couple of questions.

I have a couple of questions that I hope someone out there can answer!
Before anyone suggests I "search" I already did, but didn't find my answers, if they are already out there please point me to the thread.

Question 1

I have a couple of custom made heros. They each have a good number of abilities. And there are a couple of these (like True Sight) that are givens (all of them have it). And I would like to remove the icon for it from the menu grid to make room for other things. I know there is a way to do this by editing some files, but I was wondering if there was a way to do it in the object manager. I copied the True Sight ability and made a new abillity tried deleting the icon for it, and all it did was put a picture of a bald guy where the icon should be. I also tried setting its grid position to 4-3 but that didn't work (for those that don't know, the grid is numbered on X axis as 0-3 and Y axis as 0-2, so 4-3 would put it off the grid) it kept changing back to 3-2 when I did that. I also tried setting it to a space already taken and it just jumped to the next availiable space. Which can't happen because the hero has abilities he/she wil learn when they level up that need to take those spaces.

Question 2

The hero limit (including the one that stops you from having 2 of the same hero) doesn't work on custom heroes. On a map with custom heroes you could have 6 heros if you wanted.
I set a trigger that stops people from having more than 1 of my custom hero. This one:
I put the following in the Map Initialization Trigger:

Action
Player group - Pick every player in (all players)
-- Then for the Loop action for above action
player - limit training of (**** ) to 1 (picked player)

where **** is my custom hero.

Then for each of my additional cust heroes I can just put another
player - limit training of (**** ) to 1 (picked player)
in the loop action.

But that doesn't stop people from having more than 3 heros total. Any suggestions?

Question 3

The tree bridge is a huge tree, that when its life is reduced to zero it falls over splitting open and making a bridge (Has a cool looking animation for it too!).

I know I could use a trigger to make the trees life = 0 when I want it to fall.

But I would much rather have it be attackable and have it fall when killed, unfortunatly when playing a level that uses the tree bridge the tree is not selectable or attackable. I have already played with the object editor and still have yet to find a way to make it selectable/attackble. No matter what I did it was not selectable, but I did get its life bar to show on mouse over, and I was able to destroy it using Attack Ground.
Any other suggestions on how to make it attackable?

For question 1, instead of giving the hero true sight, you could try creating a custom unit with true sight that is hidden and follows the hero. I not sure if this is a good idea though.

For question 3, maybe you could try make a new unit with the model of the tree. I'm not really sure if this would work though.

Edit: Oh yea... if you want the tree to be cut down in a cinematic you can also try to make a unit move to the tree and make him do his attack animation, then set the tree life to 0.

For 2, I'm pretty sure that is solved with the field 'Techtree - Dependency Equivalents.' Set that to any normal hero.

I think that will fix it.... Just use the standard melee game hero limit action with it.

When I said truesight I was giving an example, there are multiple abilities that are common to all of the custom heroes.
