Heightmap Problems?

Philip Ramsay · 2013-04-17T12:09:26

Hey everyone, I posted a while back about having issues with heightmaps. I was on Easter break from university so I had to try and get help on-line but I couldn't really understand what I needed to do. I started back at university yesterday and asked my tutor to take a look and he couldn't make help me, he didn't seem to understand the code which is annoying being as I went off the tutorials supplied by my university which were made by said tutor. I'm still seriously stuck on this and I'm starting to run out of places to get help. Could anyone please help me? My code is a bit long to actually put on the post, besides it's better off if someone who knows what they are doing can see the entire thing so they know exactly where I'm going wrong. I don't want people giving me code or anything like that. I just want someone to look through my program, see where I'm going wrong and talk me through how to fix it, I really want to be able to understand this better. Any help is greatly appreciated. Edit: Just to mention the problem I'm having is that my car in my game is just hovering at a fixed height and phasing through the high sections of the heightmap. As far as I know all the code to alter it's height etc. is there, it just isn't doing anything. Here are just the source files instead of having to download a full program: http://www.mediafire.com/download.php?dwbh8ws11t4oys8

Ok, good news and bad news.

Good news is, I finally got it to work! my car is adjusting it's height according to the heightmap.

Bad news is, I'm now underneath my heightmap for some reason.

Always by the same amount? Don't you need to add the car size? Is you car scaled maybe?

Currently working on a scene editor for ORX (http://orx-project.org), using kivy (http://kivy.org).

Hey sorry I went quiet yesterday, I needed a break. Looking at it today I have actually changed the scale of the car in the properties.

I'm guessing I need to multiply or add the scale of the car to the line that changes it's Y position on the heightmap?

Actually scratch that I've changed the camera around so I can look around and I'm actually way above my heightmap, it looks tiny from where I actually am.

Ok great news! My car is finally sticking to the ground as it should! The frame rate is dropping a little when the car moves forward but I'm sure I can fix that somehow, it is only a minor problem after all.

Just want to say thanks to everyone that helped me out on this otherwise I'd have never got it done.

Thanks everyone!
