text info1
{
pos_x = 4;
pos_y = 10;
layer = 15;
string = "";
flags = visible;
}

entity* Max2_MDL_001;

action displayinfo1
{
Max2_MDL_001 = me;
var i=1;

while(i)
{
if(vec_dist(me.x, plBiped01_entity.x) > 150)
{
info1.string = " ";
wait(1);
}
else
{
info1.string = "this text appears when u get near the char";
i=0;
}
}
}

try this.


EDIT:
though it wont work
you said trhe while function only works as long as i is 1. but when you write the text, the while will be closed, so you can't copy back the text ot nothing.

just do
while(1)
{
your code
}

instead of
while(i)
{
your code
}

and dont use i then .
like this:
Code:

---

action displayinfo1
{
  Max2_MDL_001 = me;

  while(1)
  {
    if(vec_dist(me.x, plBiped01_entity.x) > 150)
    {
      info1.string = " ";
    }  
    else
    {
      info1.string = "this text appears when u get near the char";
    }
  }
}
