Hi!

I've written a routine for a player to walk up and down in a stair.
The model for this is not an external model, it's several objects placed next to each other making to illusion of a solid staircase.

Each object represents one step and is made up using the command
'make object box'
Using this method makes me able to calculate the height of each step which is crucial for my routine to work.

But what if I'd load a 3D model that is a staircase in it's entirety?
Mayby I can access the vertexdata somehow to split this thing up into several objects allowing me to read the height of each step?
What I'd need to do is reading the structure/polygons of the object to make the player object follow it ( just like the functionality of the commands for following the contour of a terrain)

Anyone that knows the best way of doing this? Thoughts? Ideas?

Best!

if your climb animation is constant you could very easy base the height of stairs on that, it minimises work being done then for your char by the cpu/gpu, this is a normal way in games from my observations, after all in real life step height are pretty standard for stairs

I would use Intersect Object(). Cast a ray from above the player downwards to the staircase and the distance will be returned which you can calculate the height from. If you like you could precalculate this and store it for later.

It's possible to do this with vertexData commands but intersect object would be the quickest/easier way imo.

Hi there.
As Fallout says, intersect object is ok...or even better using sparkys collision that is free.

Cheers.

I find sparkys collision rather complicated to use, probably because I've never found the time to learn it, so I'll stick to the native commands for now. But if I can't get it to work with intersect object somehow,,, mayby I'll turn my head to sparkys
