no.. setRotation() sets the rotation relative to the parent... not absolutely

Good point.. I stand corrected... the main thing here is that its relative... and he was trying to use it as an absolute

No problem...

also note that setRotation() is a RELATIVE rotation.. from the current position... not absolute, therefore, you will have to track the position yourself and then call setRotation() to move a relative rotational distance from the current position

One thing that jumps out at me is the following.. nodePosition.X += MOVEMENT_SPEED * cos((nodeRotation.Y) * 3.14 / 180); nodeRotation.Y is in degrees and you are sending that to the cos function and converting the result to radians... you need to do the conversion BEFORE sending it to the cos functi...

Without seeing your code its hard to tell what might be wrong... however you might consider this...

make sure that you have the triangles vertices arranged in a counter clockwise fashion when viewed from the outside of the face

make sure you have calculated the normals for these faces correctly

Are you looking for something that will actually animate the rotation? The setrotation() function will simply perform rotation in the 3D sense, that is the object will be rotated into a particular position.. if you are looking to spin an object, then you can either use an animated mesh object or pro...

rememeber, setrotation is a RELATIVE rotation and if your calculations are off even by a slight bit, and the function is called numerous times.. it will appear to be showing a slight rotation...

setrotation first converts the degrees to radians by multiplying the angle by DEGTORAD64 and then calculating the sine and cosine in order to apply the rotation... THEORY: the trig value of sin(0) = sin(360) = 0 and cos(0) = cos(360) = 1 PRACTICAL: sin(0) = 0 sin(360) = sin(360 * pi/180) = sin(.0174...

Indeed.. the differences are stark... however.. I think some are missing the main point here... and that is... that the better choice for them is not VB.. but C++

Technically you are absolutely correct... C and C++ are two different entities.... however, I used C in my text since most compilers invoke C++ in one form or another anyway... I was being generic.. not to mention... I would wager that most people couldn't list the differences between the two.. I st...

You said your friend has the intentions of learning C... if he intends on using Irrlicht... now is the time for him to do just that...
