Hey,

How can I use a function to spawn an object that will always have the same Z coord, but X and Y will always be at a given distance of an object (this object will be moving..) ?

Thanks
Mark

Using ent_create, this script will spawn a new
entity from a model not currently in the 3D enviroment
and place it behind the target entity. The target can
be moving/rotating.

Code:

---

//set the model you will be using for the spawned entity
string spawnEntity = "yourModel.mdl";  
//
//
//set the distance from the target entity you want to spawn to
var spawnDistance = 30;
//
//
function spawnTheThing()
{
   //get outta here if there aint no target entity in the game
   if(targetEntity == NULL)
   {
      return;
   }

   //set temp to the vector of the target entity	
   vec_set(temp.x, targetEntity);
   
   //this is the same idea used in a 3rd Person Camera
   //it will place the spawned entity behind the target entity
   //taking the rotation of the target entity into account
   temp.x = targetEntity.x - spawnDistance * cos(targetEntity.pan);
   temp.y = targetEntity.y - spawnDistance * sin(targetEntity.pan);
   
   //set spawnEntityAction to NULL if you do not want to asign it a function
   ent_create(spawnEntity,temp.x,spawnEntityAction);
}

Just call the function, and you'll get a new entity every time!

How do I set an entity to be the target entity?

The "target entity" is just a name i used for the example code.

You would need to use the entity name you create in your own script
and use it as a point to spawn from.

So let's say I want to spawn my object near another that already got a function, can I just use targetEntity = me ? What do I have to declare? thanks again.

If you are going to spawn new entities based
off of the location of a single entity, like a player,
then you can just use that entity name in place of targetEntity.

If you are going to spawn new entities using mutliple
entites as spawn points, you could define
entity* targetEntity = NULL, and then like you
said, point targetEntity to the entity you want to use as
a vector to spawn to.

Thanks!

Ok so heres my code:

Code:

---

//set the model you will be using for the spawned entity
string spawnEntity = "tornado.mdl";
//
//
//set the distance from the target entity you want to spawn to
var spawnDistance = 30;
//
//

action funnel
{
	my.invisible=on;
	//MOVEMENT CODE OF THE MODEL
}

function spawnTheThing()
{
   //get outta here if there aint no target entity in the game
   if(funnelEntity == NULL)
   {
      return;
   }

   //set temp to the vector of the target entity	
   vec_set(temp.x, funnelEntity);
   
   //this is the same idea used in a 3rd Person Camera
   //it will place the spawned entity behind the target entity
   //taking the rotation of the target entity into account
   temp.x = funnelEntity.x - spawnDistance * cos(funnelEntity.pan);
   temp.y = funnelEntity.y - spawnDistance * sin(funnelEntity.pan);
   
   //set spawnEntityAction to NULL if you do not want to asign it a function
   ent_create(spawnEntity,temp.x,tornado);
}

In WED, i place a little box model with the action "funnel" attached to it. In the properties box of the model, I also name it "funnelEntity".

I build, then run, then I get a lot of errors... and it crashes

thanks to help :S

before 'my.invisible = on' put funnelEntity = me;
and before action funnel put 'entity* funnelEntity;'
And btw you should post your errors
