I am making this silly game for a school project. I have made some models that are a door and a gate. I also made som models which are there for no particular use (buildings in the background). My problem is that when I play the game I can walk through my door and gate! That isn't so good considering they are supposed to be a natural blockage and you have to find keys etc. to go further.
On my models that are for no use I have checked the option BBox and then I can't walk through them. Is there anything else I should do with the doors so I can't walk through them?

I am using Gamestudio Pro version 6.60 / WED V6.751 (It's the one we get from our school)

you can use two options:

c_setminmax(me); in the function of the entity.

Or
if you use Lite-C: set(me, POLGYGON);
if you use C-Script: my.polygon = on;

or check in WED in the properties panel "polygon"

I suppose that your player model uses c_move to move.

I tried checking it as a polygon, but still I can move through my model/door. I am using player_walk_fight

I have tried my actor in another WED-project with the same model of a door and then I couldn't walk through it. That was just a tiny little level I made with just those two models and a ground. This is the only thing I need to do actually to get the first level finished. It seems to me there must be something in the self generated scripts that is bugging it up. But I'm not an expert...

something you could try is creating an action that sets the door unpassable all the time, like:

action door_solid
{
while(1)
{
my.passable = off;
wait(1);
}
}

and then see what happens.

you can also create a map entity, place that at the door's position, and make it invisible.

also, you can check(if the door is a model) if all normals are facing outside. in this case the shading wouldn't be good either, so it is easy to recognize.

I hope that one of the workarounds helps

You can open your script in SED and search for move and c_move. It must be c_move to recognize a model with the polygon flag set as an obstacle.

You can click the key F11 twice to see the collision boxes as a blue outline around the objects, too.

I tried making the action but still, no results. I also tried some other stuff but still, I'm walking through my doors. Unfortunately..

I "solved" it. I rebuilt the doors in Wed, saved it as a prefab, built it as a map entity and then problem solved. Anyways, thanks a bunch for the help and good tips. You guys are the best!
