P0x's Ladders in Darkplaces

[Ghost_Fang]

I'm sure theres been a topic of this somewhere but I didn't find it. But in a nutshell, p0x's ladders from Extras_R4 to not play nice with Darkplaces, you have to Jump up them and even that barely works. So i was wondering if there was anything in the code I would need to change in order to fix it up to make it compatible with DP.

Here is the code:

Code: Select all

void() func_ladder =
{
   InitTrigger();
   self.touch = ladder_touch;

/*   FIXME! - Physics on a moving ladder don't quite work
   // Attach the ladder to it's parent
   if (self.target) {
      self.think = train_ext_linkchild;
      self.nextthink = time + 0.2;
   }
*/
};


float LADDEROFS = 0.36;// touchy...

// This is tricky cause we can't just check key presses...
void() ladder_touch =
{
   local vector vel;
   float fvel, spd;
   
   if (other.classname != "player") return;
   
   // FIXME! - time out for teleporters?
   
   // Don't stick underwater, or in the middle of a waterjump
   if (other.waterlevel > 1 || other.fwatershifttime > time) return;
   if (other.flags & FL_WATERJUMP) return;
   
   // Don't re-grab right away if jumping
   if (other.ladderjump > time) return;
   
   // Check if the player can grab the ladder
   makevectors (other.angles);
   if (v_forward*self.movedir<-0.5)// a little more than 180¼ of freedom
      return;// not facing the right way
   
   // Avoid problems if the player is on the top edge (act like an 8 unit step)
   if (other.origin_z + other.mins_z + 8 >= self.absmax_z) {
      if ((!other.flags & FL_ONGROUND))
         other.flags = other.flags + FL_ONGROUND;
      return;
   }
   
   // Null out gravity in PreThink
   other.laddertime = other.zerogtime = time + 0.1;

/*   FIXME! - Physics on a moving ladder don't quite work
   // Factor in the parent train's movement
   if (self.owner) {
      
      // Stop all vertical movement
      other.velocity_z = self.owner.velocity_z;
      
      // Check if the player is moving sideways (don't go up/down)
      if (v_right*(other.velocity - self.owner.velocity) > 25) {
         other.velocity = self.owner.velocity;
         other.origin = other.origin + v_right*0.5;
         return;
      }
      else if (v_right*(other.velocity - self.owner.velocity) < -25) {
         other.velocity = self.owner.velocity;
         other.origin = other.origin - v_right*0.5;
         return;
      }
      
      // Get the player's forward speed   
      fvel = v_forward*(other.velocity - self.owner.velocity);
   
   } else {// Stationary      
*/   
      // Stop all vertical movement
      other.velocity_z = 0;
      
      // Check if the player is moving sideways (don't go up/down)
      /*if (fabs(v_right*other.velocity) > 25) {
         other.velocity = '0 0 0';
         return;
      }*/
