Spaceship Steering

[Biber]

This thread is about the spaceship steering.

Project Page

I developed a class, which can steer a node. There are functions which rotate the node in every 6 directions plus a function, which moves the node forward. The speeds and acceleration in for every function are controlled by parameters.

Next I had to implement an interface, so that the functions can be controlled by user input such as keyboard and mouse.

cool, I liked the steering you showed us on Wednesday.
I'm very interested how it will work with mouse-steering and in collaborating with the AI.

This afternoon, I took the liberty of having a look at the steering code. And I came to the conclusion that now it is fine.

But I was able to fix the problem anyway. It was located in the initialisation of the input system. According to the Ogre tutorials on input (buffered or unbuffered), you have to set the "mouse clipping size" (whatever that means exactly). I did that just before the rendering starts and now it works.
Actually, one would have to do this every time the window size changes, so at the moment it is just a hacky fix.

The lines I added are the following:

Code: Select all

		unsigned int width, height, depth;
		int left, top;
		ogre_->getRoot()->getAutoCreatedWindow()->getMetrics(width, height, depth, left, top);

		const OIS::MouseState &ms = mouse_->getMouseState();
		ms.width = width;
		ms.height = height;

Nice

Great, thanks!

With my usb mouse it works fine (the acceleration is a bit too fast I think, though), but it doesn't seem to like my touchpad!?

And something else: I think key up(accelerate)/down(brake) are switched. Can anyone confirm that?

edit: I think there might be a camera problem, because the code for move_forward/backwards should be fine (had a short glance at it).

[x3n]

Yes, reto inverted the camera coordinates (at least that's what I've seen in the commit-mail)

[Dorian]

It depends on what you set the cam corrdinates in the level file (sample.oxw). Perhaps one should change this so that the steering checks for the right settings itself...

[1337]

Strange, I simply copied the code from the example framework. And what do these line have to do with the camera?

[x3n]

I was talking about this (in rev511):

- cam->setPosition(Vector3(0,0,+250));
+ cam->setPosition(Vector3(0,0,-250));

[1337]

?? I have not even seen this line yet.. so I can not help with this one.

[nicolasc]

The camera should be behind the object, not in front of it and the z axis points into the screen.

[greenman]

Is it possible, that the steering only affects the camera at the moment? If I move the mouse I think, that I only see the same scene from a different angle?!

[1337]

That has been fixed by now.

I would like to conduct a little survey on the "invert axis" subject: Who actually likes the inverted y-axis?

[hofzge]

It would maybe better to make e real poll about that. You can start polls by starting a new topic... just in case you didn't know. I don't think that many people will answer here.

I, for one, like uninverted mouse steering.

[beni]

The question is only what should be the standard. Many people use the inverted mouse, so this is one of the first things that have to be made settable.
