This is saying if ( dbLeftKey is there, do this.);

I think your problem is that you have to say

if (dbLeftKey() == 1);

To make sure that it is when it is PRESSED down, not just there.

no, if leftkey is being pressed down then dbLeftKey() returns true(1). So if the left key is down it resolves to if(1){} if not then its if(0). therefor it does ask if the key is pressed. it problem is somewhere with the keystates.

I'm not a 3D type but let me ask this.

Does dbRotateObject(1,pitch,angle,roll) tell it to pitch, angle and roll to whatever the set values are or does it tell the object to rotate by those values from their previous angle?

it tells it to rotate to that angle. to rotate from you would have to do a dbObjectAngleX(object id)+anglex, ect...

Just a thought:

Try removing the ==1 from the keystate tests(if it works for the left & right tests, it might work for the others.)


Whatever...

You are calling dbRotateObject each time, regardless of whether or not a key is down, which causes the objects orientation to be added by the values you give. As long as pitch, angle, or roll is not zero, the object will rotate because they are never set back to zero. You could use dbSetObjectRotation if you want to use absolute degrees, or just set pitch angle and roll back to zero if their keys aren't being pressed.

ironstream: lol you caught it and mentioned it before I did.

yeah, setting the pitch, angle, and roll back to zero after the rotation is called would be best. I don't think there is anything else to remedy the problem while keeping the code you have there.

even if you check for a pressed key before checking which key is pressed wouldn't remove the rotation problem. It would mean, if any key is pressed, regardless if it is the one's you've chosen, the ship would rotate since the values aren't returned to zero.
