Well thats because the joy_force.x/y values are not zero most of the time. This means you would have to use a threshold value before the actor reacts. So one method that comes to my mind right now (there are several others and I bet even better ones):
VECTOR forceVec; // our vector we will set depending on joy_force and use for rotation - global definition or local but not in a loop!
var forceThreshold = 0.1; // our threshold value, adjust this if needed
...
// in the function:
vec_set(forceVec, nullvector); // reset our forceVec
if(abs(joy_force.x) > forceThreshold)
{
forceVec.x = sign(joy_force.x);
}
if(abs(joy_force.y) > forceThreshold)
{
forceVec.y = sign(joy_force.y);
}
vec_to_angle(my.pan, forceVec);
my.pan -= 90;

joy_force probably isn't the cause of the problem it more than likely lies somewhere else in your code. simple test: create a level that only rotates a simple object and see if the problem continues
#include <acknex.h>
#include <default.c>
action the_player(){
while(me){
vec_to_angle(my.pan, vector(sign(joy_force.x),sign(joy_force.y),0));
wait(1);
}
}
void main(){
wait(1);
level_load(NULL);
ent_create(CUBE_MDL, vector(150, 0, 0), the_player);
}
if you still have the problem display joy_force.x and .y to determine if they're not resetting and what their values are
...
DEBUG_VAR(joy_force.x, 20);
DEBUG_VAR(joy_force.x, 20);
if these are showing there's still problems try it with a different joypad. if these aren't the problem post some more of your code as the problem is elsewhere

The problem probably is that you, Funeral, did not adjust the variable
var forceThreshold = 0.1;
as Xarthor suggested. Try a higher value. I think I use a similar approach with a threshold of "0.3". yes i did tried with higher and lower values.. joy_force probably isn't the cause of the problem it more than likely lies somewhere else in your code. simple test: create a level that only rotates a simple object and see if the problem continues
#include <acknex.h>
#include <default.c>
action the_player(){
while(me){
vec_to_angle(my.pan, vector(sign(joy_force.x),sign(joy_force.y),0));
wait(1);
}
}
void main(){
wait(1);
level_load(NULL);
ent_create(CUBE_MDL, vector(150, 0, 0), the_player);
}
if you still have the problem display joy_force.x and .y to determine if they're not resetting and what their values are
...
DEBUG_VAR(joy_force.x, 20);
DEBUG_VAR(joy_force.x, 20);
if these are showing there's still problems try it with a different joypad. if these aren't the problem post some more of your code as the problem is elsewhere hmm yes maybe, there's a camera code that also uses "vec_to_angle" maybe that is? this is the code: var distance, angle; VECTOR temp; distance = 200; while(1) { if(player) { camera.x = player.x-distance*cos(angle); camera.y = player.y-distance*sin(angle); camera.z = player.z+20; vec_set(temp,player.x); vec_sub(temp,camera.x); vec_to_angle(camera.pan,temp);

it works well and its what was looking for, except for one detail: the player just keeps spinning around non-stop when the joystick its not moving, so which part of the code needs to be fixed?
