getting rotation on only one axis

[3DModelerMan]

Hi I am trying to implement local transformations, so I have to get the characters rotation vectors, but when I try to get only one, like this

Code: Select all

wolf_X_vector = main_player_wolf->getRotation().X;
wolf_Y_vector = main_player_wolf->getRotation().Y;
wolf_Z_vector = main_player_wolf->getRotation().Z;

I get a compile error, but when I take out the .Z etc, it compiles fine. What's wrong here?.
Thanks .

I get a compile error

Yeah, I also get compile errors some times, but there are so many different compile errors possible !!!

and is this your actual code snippet or just an illustration of what you did ???

or shall we simply guess !?!?!

don't feed the ....

Let JP handle it.

I guess that wolf_X_vector, wolf_Y_vector, wolf_Z_vector are vectors like the names say and you are trying to assign an integer to a vector^^

Aren't they floating-point values? At any rate, the compile error should give enough information for you to deduce the problems.

Code: Select all

core::vector3df rotation = node->getRotation();
irr::f32 rotX = rotation.X;
irr::f32 rotY = rotation.Y;
irr::f32 rotZ = rotation.Z;

I would assign them to specific stack variables, but rather I would just use them from the vector. Simple as that.

But anyways. If you want real help, then post real code snippets for people to help you with. It just so happens that this was easy to find out. (If that is even the problem, because you could have just named the variables with a 'vector' not even knowing the definition of what 'vector' means.) But at the end of the day, we don't know, because your code snippet didn't give enough information.

That was my exact code snipet. And thanks .

No problem.

I really apreciate the help you guys have given me so far, even though my questions are kinda dopey.
Thanks .

And by the way, it worked!, now all I have to do is search for what the math to move it was.

Your going to want to use trigonometry. Specifically the functions sin() and cos().
