I created this Script: Code: function rotate(h_direction) { while(sign(ang(h_direction - player.pan)) != 0) { h_directionset = sign(ang(h_direction - player.pan)); player.pan += (h_directionset20)time_step; if(fraction(player.pan) >= 0.5) { player.pan = integer(player.pan)+1; }else { player.pan = integer(player.pan); } wait(1); } } This rotates the player to an angle i choose. In my RPG, they are 0 / 360, 90, 180, 270. The Problem: Wehn the FPS are low, the player looks like he is shaking... Do you know a better way???

Then, when you quit the while loop, correct the tiny deviation in the angle to the exact rotation it should be facing. Click and join the 3dgs irc community! Room: #3dgs

uhm.. plz don´t think i´m stupid.. but.. can someone comment out this code:

Code:

vec_set (temp_enemy_rotate.x, destination_node.x); 
vec_sub (temp_enemy_rotate.x, my.x);
vec_to_angle (temp_enemy_rotate_2.x, temp_enemy_rotate.x);
if(my.pan == temp_enemy_rotate_2.x)
{
my.pan=my.pan;
}
else
{
rotate_result = ang(temp_enemy_rotate_2.x - my.pan);
if (rotate_result > 0)my.pan += 20 * time_step;
if (rotate_result < 0)my.pan -= 20 * time_step; 
if ((ang(temp_enemy_rotate_2.x - my.pan) < 0) && (rotate_result > 0))	my.pan = temp_enemy_rotate_2.x; 
if ((ang(temp_enemy_rotate_2.x - my.pan) > 0) && (rotate_result < 0))	my.pan = temp_enemy_rotate_2.x;

because i think i´ve a blackout.. can´t say how this should working with a 90° by 90° rotation.. >.<

If the palyer shoudl rotate to 180, do i need to call it like that: BotTurnTo(my, vector(180,0,0)); ??? Selling my Acknex Engine Editions (A7 Com & A8 Pro): >> click here if you are interested <<
