I'm having trouble figuring out a way to rotate a ship around it's Y axis and then having it move forward in the direction it is facing.

can anyone guide me in the right direction? i'm sorry for the pun

Assuming "math.h" is included you can just:



and remember that these angles are in radians, if your 'yAngle' is in degrees then just * 0.0174532925f to make it radians.

dbRotateObject(objID,dbObjectAngleX(objID),dbObjecdbObjectAngleY(objID)+1,dbObjecdbObjectAngleZ(objID));
dbMoveObject(objID,1)

Should work

Look up the dbNewXValue(), dbNewYValue(), and dbNewZValue() functions.

I of course meant * ( 180.0f / pi ), and not its inverse :p.

Remember - You might have a rotate + fix pivot yet to implement.

Is your ship "almost working" but flying up - or right always? If so, it could be you need to rotate the thing to make it so the FRONT you want really becomes the FRONT - you rotate to desired angles, then call fixpivot (dbFixObjectPivot or something)

then you might be a bit closer to what you're looking for.
