On a right mouse click or on hold the right mousebutton the player should rotate to/or with the mouse cursor. So now if i pressed the right mousebutton the player rotates to the north maximum 90�. why? he should rotate 360�. Ok i am not really understand the vector thing but maybe anyone have an idea and could help me please. I hope you understand my bad english Thanks a lot oODarkPassionOo Last edited by oODarkPassionOo; 10/27/11 15:27.

So it is very difficult to hit the red ghost I think you see what i mean. How can i fix that? Code: if(mouse_right == 1) { my.pan = (mouse_pos.x) * 0.75 * time_step; vec_set(camera.x, vector(0, 0, 0)); vec_rotate(camera.x, my.pan); vec_add(camera.x, my.x); vec_set(camera.pan, vector(my.pan, 0,0)); my.pan +=180; } ok i don't understand that vector-thing and i am very thankful when anyone could explain it to me or correct the codesnipet for me. i looked in many forums and tested some code like that above. Thank you oOdarkPassionOo Last edited by oODarkPassionOo; 10/27/11 20:35.

But, the mouse cursor moves within the plane of the screen. That are two unrelated positions, to get them 'in touch' you have to transform the position of the mouse from the screen to the surface of the ground. The snippet of the manual shows how to do that. http://www.conitec.net/beta/mouse_pos3d.htm Then you can let the player turn in direction of that position on the ground with the following snippet from the manual: http://www.conitec.net/beta/avec_to_angle.htm http://www.puppenheim.org/ http://www.wuerfels-welt.de Old Game Tutorial: http://www.puppenheim.org/MITutorial.zip Free Game Editor: http://puppenheim.org/AlienalsWeihnachtsmann.zip http://www.puppenheim.org/blender_starting_main_settings.txt

Anscheinend fehlt mir da der Teil im Gehirn der f�r Vektoren bestimmt ist Ich probiers auf deiner Grundlage mal weiter und vllt schaff ich es dann irgendwann obwohl es echt frustrierend sein kann aber das geh�rt ja dazu.
