entering buildings

i made a map where you can go into buildings (neutral shop that can load heroes) and search for items. every hero has a enter building ability that when targeted at a neutral building will make the building become owned by that unit then load the unit.
player control is taken away for about 10 secords and then the unit is unloaded with a new item in the inventory and the building becomes neutral again.

is there a way to remove the unit loaded slots that appears in the building when a unit is loaded? it shows what units are currently loaded and the maximum storage and when another player besides the loaded unit player clicks the loaded units portrait in the building, the unit is forced out

even enemies can unload you from building by clicking the loaded unit portrait in the building so is there a way to take this out? or some way to make it unclickable for anyone?

Can't you just hide the hero and play the load sound? For enemy units you can just pick all alies of current owner and if the owner of casting unit doesn't match picked player then don't let them in. If not then your alies hero can still get in and since ur not useing the load ability anymore, your hero won't get kicked out.

Remove Select Hero from the building when someone enters it

That only allows 1 person to go in.... and he wants his allys to go in also.
Please read the question carefully first before you post.

Or hide the building after the hero enters and create a new empty building.

It is better making your unit that which is about to enter a building Neutral Passive. Then you have a trigger ordering it to load into the building. After a set time passes, u order the building to unload your unit. and transfer control of the unit back to the previous owner.

------------------------

Alternatively u can stop your enemies or anyones else from entering the building by disabling the gain control of buidling trigger for that particular buiding. and then enabling the trigger again when you unit leaves it.

Im not sure exactly what your trying to do here but, I made a map once with a waygate that looked like a building. When you went through the way gate you were teleported to an enclosed space that looked like rooms with tables chairs etc... The way gate to get out looked like stairs. It had a pretty nice effect. It looked like you were physically going into the building and you could move around inside for whatever reason.
