Proportional speed movement between mouse and cube
- by user1350772
Hi i´m trying to move a cube with the freeglut mouse "glutMotionFunc(processMouseActiveMotion)" callback, my problem is that the movement is not proportional between the mouse speed movement and the cube movement.
MouseButton function:
#define MOVE_STEP 0.04
float g_x=0.0f;
glutMouseFunc(MouseButton);
glutMotionFunc(processMouseActiveMotion);
void MouseButton(int button, int state, int x, int y){
if(button == GLUT_LEFT_BUTTON && state== GLUT_DOWN){
initial_x=x;
}
}
When the left button gets clicked the x cordinate is stored in initial_x variable.
void processMouseActiveMotion(int x,int y){
if(x>initial_x){
g_x-= MOVE_STEP;
}else{
g_x+= MOVE_STEP;
}
initial_x=x;
}
When I move the mouse I look in which way it moves comparing the mouse new x coordinate with the initial_x variable, if xinitial_x the cube moves to the right, if not it moves to the left.
Any idea how can i move the cube according to the mouse movement speed?
Thanks
EDIT 1
The idea is that when you click on any point of the screen and you drag to the left/right the cube moves proportionally of the mouse mouvement speed.
