Hello

I'd like to use "c_rotate..." instead of "pan + = ..." in the following snippet (from the kh-movement code).
Would be great if someone could help me with this

Code:

---

function rotate_entity(rotate_angle,rotate_speed) {
	if (my.pan == rotate_angle) { return; }
	result = ang(rotate_angle - my.pan);
	if (result > 0){
		my.pan += rotate_speed * time_step;
		}
	if(result < 0){
		my.pan -= rotate_speed * time_step;
		
	}
	if (ang(rotate_angle - my.pan) < 0 && result > 0){
		my.pan = rotate_angle;
	}
	if (ang(rotate_angle - my.pan) > 0 && result < 0){
		my.pan = rotate_angle;
	}
}
  

---

Code:

---

function rotate_entity(rotate_angle,rotate_speed) {
	if (my.pan == rotate_angle) { return; }
	result = ang(rotate_angle - my.pan);
	if (result > 0){
		c_rotate(my,vector(rotate_speed * time_step,0,0),ignore_passable);
		}
	if(result < 0){
		c_rotate(my,vector(-rotate_speed * time_step,0,0),ignore_passable);
		
	}
	if (ang(rotate_angle - my.pan) < 0 && result > 0){
		c_rotate(my,vector(rotate_angle - my.pan,0,0),ignore_passable);
	}
	if (ang(rotate_angle - my.pan) > 0 && result < 0){
		c_rotate(my,vector(rotate_angle - my.pan,0,0),ignore_passable);
	}
}

dunno if this works... instead of just ignore_passable, you might also need to add use_axis... I never get that right...

Hello Loopix! Remember me?
I know, how it's mad function > in help file they haven't written that fact, that c_rotate adds angle, not sets it.
Here is example script:
Code:

---

action ent1111 = 
{my.shadow = on;
while(1)
{c_rotate(me,vector(1,0,0),IGNORE_PASSABLE);wait(1);}}
function main()
{video_window(nullvector,nullvector,1,"c_rotate test");video_switch(8,0,1);
fps_max = 64;detail_size = 64;vec_set(sky_color,vector(192,160,128));
level_load("map_water.hmp");wait(3);ent_create("hover.mdl",vector(-256,0,128),ent1111);}

---

That rotates ent's pan 1degree per sec. so, you need just to replace
Code:

---

my.pan+=rotate_speed * time_step;

---

by
Code:

---

c_rotate(my,vector(rotate_speed * time_step,0,0),IGNORE_PASSABLE);

---

also replace result by some var, for example
Code:

---

var temp_integer;

---

to avoid conflicts with c_rotate.

I just noticed that Germanunkol has sended reply while i was typing.
But hes said right, except result because its modified by c_rotate and Code:

---

my.pan = rotate_angle;

---

because back rotation can cause lag, and isn't needed because first c_rotate already checked its way.

Hey...thanks guys! I got it working now Vadim647 is a really helpfull new member of the community...he's so young and so clever

A thank you from me also. Just few questions to Loopix:

Have you replaced trace with c_trace and also did something to the collision? ATM i'm using the default USE_AABB from KH Movment tutorial, because if i'd use something else I get strange results. If I keep using USE_AABB all is fine as long if you dont step onto another model, then it push the player upwards.

Below is the half finished movement script from kh movement tutorial. Loopix ff you have some spare time can you look at your c_trace and c_move and tell me if they use USE_AABB, or maybe explain me how you fixed the collission problem with mdls and such?

Yeah...I use now c_trace/c_move/c_rotate only and everything works well so far I use "c_setminmax(me); wait(1);" at the begining of every acting entity and the c_move/c_rotate mode is "ignore_passable + ignore_passents + ignore_me + glide"

Actualy I use only the animation blending from kh-movement code...I'm working on a simple and easy modable close combat template wich I might release soon (free!)

It's not so needed to use wait(1); then. It works correct even without it.

Thanks again. Have hard time with understanding the collision system. Tried replacing the USE_AABB with those commands you've used. And it works although I can't jump anymore. Looking forward to your release. Perhaps I can use that for learning

Removed the wait(1); before c_setminmax(me), but is this not required if you set symetric box of the model? With A7.08.0 beta i've got some strange results after removing USE_AABB and setting GLIDE (camera/player keeps jumping) enable_polycollision is set to 2 as i'm also using physics. Will keep trying though.
