hi there!
i would like to know how to make enemies walk on custom objects. when i put an enemy on the roof of a stock media object and start the game the enemy starts chasing me and walks around to find me.
when i put an enemy on a custom object and start the game the enemies don't chase me when they see me. they shoot at me but they don't move.

on these objects i have another problem: when i want to place an object an the surface of f.e. the oilplatform it doesn't snap on the auto height, i follows the surface of the underground and i manually have to lift it up and place it.

affected by this are two objects i use. one is the oil platform and the other is a tunnel system i got from the forum. all the objects have forcesimpleobstacle = 3!!

is this a problem of collision mode?

This can not be done yet at all with AI or characters. All you can do is place them up there with isimmobile=1 to keep them from falling thru the entities. They should still shoot at you this way. But this feature does not exist yet in this build. They will not walk on anything that is not the terrain or that is thicker then 5 cm from the terrain.

Some objects you will have to place up and down manually. The vertical snap is based on where the pointer is to where the relationship to the object you want to snap it on top of. If there are entities above it, it will want to go to the highest entity.

You will have to manually adjust some objects into place.

We are still figuring the best, performance friendly way of getting characters to walk on 'anything'. The closest ideas we have so far is to 'paint polygons' which then turn into a live 'nav-mesh' so you can define which areas your characters would walk on, be that rooftops, stairs, floors, custom objects and so on. We want to avoid turning 'everything' into a nav-mesh surface as it would gobble more memory and require a larger traversal of data by the AI system. A simpler idea we had was to create a new 'zone' which had a height property so you would effectively define a boundary and a plane within which a character could maneuver, but this would effectively 'cage' enemies into the level. The ideal of course is that the enemies could go anywhere the player can, and we've also experimented with this level of capability but required so many animations from the character that it got a little crazy. We're getting closer to the day we will be implementing a solution for this, so watch this space as we agree it's a key feature for sophisticated game levels.

ok, thanks for the quick response!
so there would actually be no way to make my enemies move around on the oil platform? that would be a pity and ruins a great level idea for me (again)

+1
this is a essential feature.

Your ideas are not ruined, they just cant be completed. This is still early access program and to even think of making a finished game right now will make you bash your head into a wall. This early access stage is for testing features and limitations of the software.

I have dozens of projects waiting for finished features, but even still, are not even considering making anything for keeps.

Things change and the way it worked 3 weeks ago, may not be the way it works 3 weeks from now.

God no as Myke states .... don't just give up on the map .... it isn't ruined ... we all have ideas of putting characters on different levels and many have maps we can add to later ...me included ...

yep I have made a few as well fully knowing I cant add characters to second levels yet .... but there ready for when I can
