Hello, I have been messing with trying to get a chase cam to work properly and have a vehicle that is centered in the screen, that you look down on kind of at an angle, and allows you to drive around a plane with buildings etc.. on it, and it keeps your vehicle centered and at a certain distance away from the camera, I am not having much luck, I went from it halfway working and the vehicle would rotate properly but when moving it looked like the vehicle was moving down into the terrain instead of forwards and backwards. Also, now on my second attempt I am unable to see a plain I created and textured at all, all I am getting is a black screen, what am I doing wrong ? Does anyone have a really simple example maybe using cubes for objects or something ?

PS. I think the reason I can't see anything, is it has something to do with the distance at which the plain is located from the camera, but not sure how to rotate it, or how to ensure the camera can see it correctly.


Thanks in advance.

Well, its quite hard to understand what you are saying. Post your code in here so people can take a look at it and try to help you. Once you throw in your code, I will be able to help you.

That is hard for me to do at this point, I am at work, but at lunch I will pull up my code, on my portable and retype it in here, to submit the code to this forum posting for you to look at.

Phew.. There.. I had to retype all of that by hand.. whoa, hands are a little sore after that.

Hope this helps you figure out what I am doing wrong with the camera and why I can't see the plain or land object in the view.

Thanks

Ken

Okay I figured out what was wrong on my own, after looking at my code and looking at an example, I realized I was missing the very important sync statement.

Thanks for the help though, any other help on movement and physics etc.. would be greatly appreciated. I will also post the vehicle loading and what I have for movement so far tonight when I get home.

Just a note, I don't know for sure on this, but I think that Sync Rate 60 is not even being used. I think that command is only useful for when you have SYNC OFF. Again I don't know for sure on this, but it would make sense.

Thanks for the info, I still need some more assistance, I now have the vehicle loaded, and the plain textured and lit correctly, and have the vehicle moving, but I need to attach the camera so that it moves with the vehicle at a steady rate, and rotates with the vehicle as well so the player can drive all over the terrain, anyone have any example code showing some fake physics even, or can someone explain better how to use the newton game dynamics library ? I looked at the examples but not sure how to use it to make my vehicle move, and make my buildings fall etc.. and animate exploding when they are hit at a certain speed by the vehicle.

Thanks,

Ken
