How do I make a building become invisible?

[Eagi]

Hi I'm making my first Rpg in MMF2
as you can see below I have an Idea on how I want the interaction with buildings to work.
If you walk in front of a building I would like it to act as a background not obstructing the player.
But if you walk around back it would be cool if the outline of the building would disappear and only
leave the base as a marker of where you cant walk. Is there an easy way to achieve this or should
I rethink my layout?

I was thinking something along the lines of making a separate object of the base that is used as an
obstacle and then making the outline into an active object that will go invisible when you step onto
the area that represent the backside of the building. Would this work or do you have a better
suggestion?

Thank you all // Ed

As I understand your idea - i guess i would do it the same: 1 object as a physically object with collision. 1 for the graphics. When getting close to the roof (or whatever you want to have) I would change the transparency / alpha value in a smooth way till it gets 100 percent transparenc (every 4ms alpha of object -1). But I dont know if I understood your problem.

Not really a problem yet, I'm totally new to this, and haven't learnt even the basics yet. So I'm mostly looking for conformation of whether my design ideas are feasible or not.

Tank you for the tip, about gradual transparency I might get back to you for aid when the time comes

I've included a simple example file below of what you do to change the semi transparency. It's very simple so you should get the hang of it right away.

iamjot's method is much nicer but the example I'm showing is just a basic fade to get you started. Rather than fading away, the building simply goes semi-transparent so you can still see the building but also the character through it. There's a plain black tile dumped underneath this which is then seen when the house goes semi transparent.

If you want no outline at all, you can just change the semi-transparency to it's full value of 128 or just make the house invisible.

Take a look at the events in the example attached.

Thanks! really nice instructions, hard to believe how helpful everyone is around here.
