Mood: Exasperated. Ranting.
As I have posted in previous threads, I am learning Blender (and Python) only so that I can plunge straight into a game project that is far, FAR beyond my current capabilities (hence the motivation for learning).
I’m trying to learn a certain simple concept. I’m having trouble putting into words what it is, but that doesn’t really matter: I can learn this while working on a smaller project. I think that I will be able to learn this… thing… IF someone explains to me how to make a somewhat realistic car that drives around, using the game engine. When I say realistic, I mean that the wheels spin around some local axis, and that the friction between the wheels and the ground drives the car (as a whole) forward.
Actually, scratch that. You can skip telling me the code about turning the wheels, because that’s not important. What I want is for someone to tell me how to make the car body and the four wheels behave as if they are joined together (at imaginary axles).
Heck, if you won’t even tell me this, tell me where I can find out. Point me to something that I haven’t seen before. Tell me how I’m supposed to learn this. I went to the blenderwiki. I clicked on “Game Engine Documentation”. I’ve completed the starter tutorial. The FAQ doesn’t tell me anything I currently want to know. The link to the “User Manual” contains ONE SORRY DOCUMENT DETAILING THE USE OF TEXTURES.
Please, please don’t tell me to look around, experiment, and learn how to do it myself. I’m already trying that. It’s led me to a dead end. I found it very difficult to make the progress that I’ve managed to do. There doesn’t seem to be any standard documentation for Blender at all, and the stuff at blenderwiki and noob-to-pro seems badly written/very incomplete - especially the stuff on the GE.
I downloaded a set of demo files, specifically so that I could look at the programming for a car. The first line is:
I’ve never heard of this module before. It’s not mentioned here anywhere:
Where can I find the documentation for this module?
After a few rewrites, what you see above this sentence has become more and more ranty over time.
In the short term, I would greatly appreciate if someone would explain to me how to make a very simple vehicle. I’m talking about supporting a chassis of some kind on a number of wheels which are able to spin around one axis.
I think I’ve almost got it.
I tried reading other threads on this subject.
What I’ve currently got is my car-body and wheels parented to an empty object. They’re all actors, dynamic, rigid body AND no sleeping.
I’m then using logic bricks in order to spin the back wheels. What happens (when I try to make the car drive forwards) is that everything seems to go into a kind of erratic orbit around what I assume is the empty object. The actual car parts now have no problem going through the plane that the car was placed above.
Then I read that I wasn’t supposed to use parenting in this situation.
Ok then. Constraints.
“Constraining” doesn’t seem to work at all. Maybe something unexpected is happening.
Perhaps people and I are talking about different kinds of constraints. I go into the Button window, select the appropriate object, click on the “object” button (F7) and try adding a constraint in that panel. While it makes a difference in the immediate display, any changes do not show up when I try running the game.
Perhaps I’m doing something wrong.
Ok then. I’ve been writing for ages, there’s GOT to be a coherent question in there somewhere.
