Need help making a 3-D shooter!

3d mesh object, yeh maybe, so they try getting it to go above 20fps with a large terrain

It would be unnecessary to use the 3d mesh objects events for collisions, rather it would be much simpler and more effective to use it as a display tool and use a 2d map/grid for collisions (with height values assigned to add yourself a 3d Y axis), as the 3d mesh object seems a tad unfinished and underfeatured at the moment (in comparison to the old 3d sprite object).

Edit: frames per second issue: that also stands until the object is HWA supported.

I dont see any other objects around?

You don't need to, all you need is the built in active objects in combination with the 3d mesh object (which would only be used for display purposes) and a little bit of alterable value manipulation for collisions and height detection, it still wouldn't be true 3d (other than the display), but thats the closest you are going to get and probably the most accurate way of doing it.

Yes that can be made with active objects.

An edited screenie of CounterStrike Source?

What exactly do you mean?

The NPC's will be really hard to make. I would try to achieve the man with no gun walking around a grassy plain being made by MMF2

That would be simple, actually, I sorta have the idea of it already. however I have little idea of how to make the NPC appear on screen, however I know how to physically (but not visibly) allow him to be placed around the field and shot at.
Actually, it wouldn't be too hard to make the enemy appear on screen, assuming you have a nice little heightmap of actives set out like I said before, and give the NPC its own hitbox height value, so that bullets traveling within its x-y-z box could strike the NPC.

I'm pretty sure the "flash" CounterStrike you just showed off used a load of screenshots and just played them out 2D shooter style, like a shooting range game.

well dynamyth make CS in MMF then, we should have a bet on if you can make it or not, I'd bet £50000 against

Haha, this is a bit rough, but it outlines my idea, sorta.
I made it in paint in like 10 seconds, its hard to understand but its got all of my info summarised with (bad) pictures.
