You have to update the string-bitmap while inkey is active. Unfortunately, inkey pauses the running function. So, you have to start a coroutine BEFORE you execute inkey which runs as long as inkey is active.

Make a new WDL file called "demo_inkey.wdl" and start it in the sample folder with the sample font to see how it works.

Code:

---

include "fontRender.wdl";

PANEL pleaseEnterName
{
   flags = visible;
   pos_x = 10;
   pos_y = 10;
   layer = 999;
}

PANEL userName
{
   flags = visible;
   pos_x = 280;
   pos_y = 10;
   layer = 999;
}

var fontArial[256];
string tempStr;
string userNameStr;

function inkeyRefresh (pnl, &fnt, strInkey);

function main ()
{
   vec_set(screen_color, vector(128,128,128));

   RF_createFont(fontArial, "arial.tga");

   RF_pnlRenderString(pleaseEnterName, fontArial, "Please enter your name:");

   inkeyRefresh(userName, fontArial, userNameStr);
   inkey(userNameStr); //function will be paused until inkey is over
   
   userName.visible = off;

   //say hello to the user
   RF_pnlRenderString(pleaseEnterName, fontArial, str_cat(str_cat(str_cpy(tempStr, "Hello, "), userNameStr), "!"));
}

function inkeyRefresh (pnl, &fnt, strInkey)
{
   wait(1); //wait to let inkey start (proc_late doesn't work for this)

   //wait until inkey is finished
   while (inkey_active) {

      //update text rendering
      RF_pnlRenderString(pnl, fnt, strInkey);

      wait(1);
   }
}
