I'm trying to implement a deployable barrier but I can't seem to place any object down in-game.

The Dispenser The Barrier and the error The model has its basic model named "body" the collision named "collision_-b-body" and an hp_active.

I had this show up once, unfortunately I can't remember the circumstances. I guess for now you could make sure your odfs are calling the correct dependencies - for example your first prefix is "cov"... I'd check to make sure you didn't name something "com" by mistake.

Thanks Oceans, but it found that the problem consisted somewhere in the dispenser and barrier odf. I cleaned everything, copied over from the stock dispenser and stock destructible buildings, and the problem was fixed. However, the barrier deploys in mid-air, at the angle I am looking at in-game. Any suggestions?

I'm not certain, but it sounds like the root of the model isn't placed correctly (or the model placed wrong in relation to the root). This could cause floating I believe. If you have xsi you can inspect the model and adjust it.

The root "dummyroot" is centered at 0,0,0 and the model is aligned accordingly.
