Title: Collision detection with pre-rendered background?
Post by: kingbear on 2010-10-12 12:34:53

Hi all,

Some great content on here!


I have a few questions relating to the collision detection (and it might be a long shot but nevertheless..) - say for example that you're in the AVALANCHE hideout in the initial few scenes of the game (http://www.creativeuncut.com/gallery-01/ff7-bg-03.html).  Notice the large pipe/pipework at the bottom of the screen.  A character collision is detected against such objects.

* How is this doable with pre-rendered scenes? 
               - Does each scene have meta data describing bounding boxes / general areas which are not traversable, etc?

* Are they actually rendered objects, textured really really well?

I just took the AVALANCHE hideout as an example, but you could also refer to the Midgar Slum Church, where the rows of pugh's are not walkable / solid objects.

Hope you can shed some light on this for me! 

Many thanks, and keep up the great work.

I don't know much about this but the game uses walkmeshes for prerendered backgrounds.

I don't recall ever seeing actual characther detection in the game but it's been a while so I might be off.

If you search on walkmesh on the forum or in the wiki, you should find more info.

Thanks again for the swift reply.
