when i run my level, in my level, my camera keep shaking non stop.
anyone know what wrong with it?

unplug your joystick mabey

This could very well be the solution if you have one plugged in. I had a problem with a demo posted here not too long ago where the vehicle wouldnt stop going backwards... Come to find out my controller was plugged in and was causing the vehicle to go in reverse.

There are a thousand possible reasons for it.

movementcode, how the camera gets mouseinputs, collisions with another entity
camera is positions with an incorrect trace that makes the camera shake.

(non updated collision hull on a dynamically altered terrain, as I had a problem
a while ago)

Bets you post your code, or make a little demo.

var video_mode=7;
var video_depth=32;
var move_vec[3]=0,0,0;
var idle_percent=0;
var walk_percent=0;
var temptilt = 0;

action display_glass
{
my.alpha = 25;
my.transparent = on;
}

action player_move
{
player = me;
wait(1);
Camera.genius = player;
while (player !=NULL)
{
move_vec[0] = (key_w - key_s + key_cuu - key_cud ) * 20 * time; //moving forward and backward
move_vec[1] = (key_a - key_d + key_comma - key_period) * 15 * time; //strafe movements
player.pan -= (mouse_force.x) * 100 * time; //using the mouse, left and right arrow keys to turn left and right
move_mode = IGNORE_YOU + IGNORE_PASSABLE + IGNORE_PUSH + ACTIVATE_TRIGGER + GLIDE; // move mode parameters to avoid sticking on walls and models
player.tilt-= mouse_force.y * -200 * time;
ent_move(move_vec,NULLVECTOR);
If (move_vec[0] == 0 && move_vec[1] == 0)
{
idle_percent = (idle_percent +5*time)%100;
ent_animate(me,"idle",idle_percent,ANM_CYCLE);
}
else
{
walk_percent = (walk_percent +5*time)%100;
ent_animate(player,"walk",walk_percent,ANM_CYCLE);
}
vec_set (Camera.x,player.x);
camera.z += 27;
camera.pan = player.pan;
Camera.tilt =Player.tilt*4*time;
wait(1);
}
}



function main()
{
level_load("Level1.wmb");
wait(2);
}

but when i reduce it the mouse movement lag
after i move my mouse for 1-2 sec, then onli the camera view move
