Hello,

I have an entity wich is going up and down (along with the z-axis). I want to make a camera mode that stays on the ground an follow the entity wich is going up or down. I have tried c_trace and c_move, but without result.

How can I fix this?

Hi,

you have to create a second entity. This could have a action like this:

action camera_ent
{
my.passable=on;
my.invisible=on;
while(1)
{
vec_set(my.x,your.x)// your.x=your entity
my.z-=c_trace(my.x,vector(my.x,my.y,my.z-5000),ignore_me+ignore_you);
vec_set(camera.x,my.x);
camera.pan=my.pan;
camera.tilt=my.tilt;
camera.roll=my.roll;
wait(1);
}
}


Haven't tested it, but it could work.

Didn't work for now. Now it's just one view straight ahead and don't follow the entity:

Code:

---

action camera_ent
{
	my.passable = on;
	my.invisible = on;
	
	while(1)
	{
		if(key_e == 1) {
			vec_set(my.x,machine.x);// your.x=your entity
			my.z -= c_trace(my.z,vector(my.x,my.y,my.z+1000),ignore_me+ignore_you);
			vec_set(camera.z,machine.z);
			camera.pan = my.pan;
			camera.tilt = my.tilt;
			camera.roll = my.roll;
		}
		wait(1);
	}
}

Haye you read my code?

Code:

---

...
vec_set(camera.z,machine.z);
...

---

has to be
Code:

---

...
vec_set(camera.x,my.x);
...

Thanks, that is working. But now I want to attach a key to it. If an user is pressing 5 the camera must be in a loop so that he follow the entity. Also if the user don't touch the button. I have the following code now:

Code:

---

action camera_ent
{
	my.passable = on;
	my.invisible = on;
	
	while(1)
	{
		if(key_5 == 1) {
		vec_set(my.x,machine.x);// your.x=your entity
		my.z -= c_trace(my.z,vector(my.x,my.y,my.z-5000),ignore_me+ignore_you);
		vec_set(camera.x,my.x);
		camera.pan = my.pan;
		camera.tilt = my.tilt;
		camera.roll = my.roll;
		}
		wait(1);
	}
}

Sorry, I don't understand this sentences:

It should follow in both cases? If yes, you don't have to write any if-condition.

Imagine. You are playing the game/simulation. You are viewing the entity. If you press the 5-button on your keyboard the camera switches to the right position (wich follows the entity of the code you gave me).

I move the entity up and down with the q/a-button. But when I do that the entity goes up, but the camera stay at one place (the camera only moves when I press and hold the 5-button). So my question is: Is there a manner to move the camera without to press and hold the 5-button. So the camera is attached to the entity?

You may place the camera in a certain distance
away from your entity, when you move the entity,
move the camera also and keep it always look at
your entity.

Code:

---

action yourEntity
{
   while(1)
   {
      // entity move code
      //.....

      // Place the camera in a certain distance 
      // away from the entity
      camera.x = my.x + 15;   // play with 15
      camera.y = my.y + 15;   // play with 15
      camera.z = my.z + 2;    // play with 2
	
      // Always look at the entity
      vec_diff(temp,my.x,camera.x);
      vec_to_angle(camera.pan,temp);
      wait(1);
    }
}

If i understand you right: Just remove the

if(key_5 == 1)

Regards

var key_5_on;

function dontknow
{
while(1)
{
if(key_5 == 1 && key_5_on == 1)
{
run +=1;
run %= 2;
key_5_on == 0;
}
if(key_5 == 0)
{
key_5_on == 1;
}
if(run == 1)
{
camera.x = my.x;
camera.y = my.y;
camera.z = my.z;
vec_diff(temp,my.x,camera.x);
vec_to_angle(camera.pan,temp);
}
wait(1);
}
}
