Problems with walls

This is the second time I try to work with walls and is really frustrating.
I'm using the ObEditor 1.5.9 and have managed to create what he wanted.
But the problem is during the game.
The characters go through the walls in the slams, or throws and disappear from the screen. Each character has the script antiwall in their movements, but still not working properly. The players and the enemies disappear and  are locked up on the screen, if you try to move, eventually falls back to the screen.
I've been thinking about abandoning the idea of using walls, but I want to use every effort to make the most complete mod.
I hope to find what the problem is.

i think antiwall script could solve your problem

i use it on my projects and works for me
check if your antiwall is that one:

Code: 
void antiwall(int Dist, int Move, int Distz)
{// Checks if there is wall at defined distance
// If there is wall, entity will be moved away with defined movement
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int z = getentityproperty(self, "z");
   float H;
   float Hz;

   if (Direction == 0){ //Is entity facing left?                  
      Dist = -Dist; //Reverse Dist to match facing
      Move = -Move; //Reverse Move to match facing
   }

   H = checkwall(x+Dist,z);
   Hz = checkwall(x+Dist,z+Distz);

   if(Hz > 0)
   {
     changeentityproperty(self, "position", x, z-Distz);
   }

   if(H > 0)
   {
     changeentityproperty(self, "position", x+Move);
   }
}

Thanks my friend!

But if you read all my post, you see i have that script in all my characters.
I post some animation, to see how use the script.

I can't understand where is the problem.

I am now on a smartphone, but when I got home, I pass the photo. Looking at your photo, strikes me the height of your walls. I see far exceed the size of the screen. In my stage, set up to only slightly exceeded. I do not know if that affects the problem.

About Maggas question,  happens in all type of slam or throws.

when are from corners and places like that, bloodbane and maxman like to set high ones at least when tehy do it for me
but there are sometimes that you need to make it smaller like in the case of my first stage, where players and enemies will jump from those walls

Thanks Maggas!

I try with the sripts, but the problem still coming.

Here a picture of this stage (original created by Illu) in ObEditor 1.5.9:

      @cmd    antiwall -50 50 -1
      @cmd    antiwall -70 30 -1

or this, where the antiwall is after the finish:

      @cmd    depost 0
      @cmd    finish 5 2 2 2 0 0
      @cmd    antiwall 30 -70 -1
      @cmd    antiwall 50 -50 -1
      @cmd    antiwall 70 -30 -1

Bloodbane teach me this:
http://www.chronocrash.com/forum/index.php?topic=1105.msg11571#msg11571

So ... what am I doing wrong?

i don know about the antiwall part but
judging by the image and your video  the problematic part of your walls are just the corners?

i edit some points in your image make a backup of your wall values and try to move a little up the places i have marked with an arrow until the places where the lines are crossing become separated (where i marked with a circle)
check if this way something changes

looking by the video i got the impression that the character and enemies are already inside the wall

Well, i try setting your values in the animation and work perfect:

I mean this:
      @cmd    antiwall 30 -70 -1
      @cmd    antiwall 50 -50 -1
      @cmd    antiwall 70 -30 -1

If the position is negative i suposse use this:
      @cmd    antiwall -30 70 -1
      @cmd    antiwall -50 50 -1
      @cmd    antiwall -70 30 -1

Thanks for all you help my friend.

I admire your work, and I want you to know that your mods of Mortal Kombat, were the inspiration that led me to be working on mine.

THANKS!

Anyone else use the method of Maggas?

Let me know if you need to set different antiwall the script, instead of copying and pasting as I did. Beyond that worked well Raiden.
But not if it be so with all the characters.

You may have other issues as well, but you defiantly need a wall checking function that only requires running once and fully shunts instead of needing to be run on multiple frames. Here's the latest version of my own wall shunt. You run it right before releasing a bound entity and it will auto shunt exactly how far is needed.

Code: 
void dc_wall_shunt(void ent, void bound){

	/*
	dc_wall_shunt
	Caskey, Damon Vaughn
	2010-05-15
	~2011-07-22
	~2015-03-08

	Shunt self away from wall if bound entity is inside of it (wall). Prevents getting
	a bound entity stuck within areas meant to be inaccesable or bounced to infinity
	by wall functions.

    ent:	Anchor entity.
	bound:	Bound entity.
	*/

    int
        wall,
        hole;

    // Anchor entity location.
    float
        x,
        y,
        z,
        anchor_b;

    // Bound offset and base.
    int
        check_x,
        check_z;

	// Verify the bound entity is valid.
	if(typeof(bound) != DC_WALL_SHUNT_VT_PTR)
    {
        log("dc_wall_shunt(<anchor entity>, <bound entity>): Invalid or missing bound entity.");
        return;
    }

	// Default to self if no anchor entity provided.
    if(typeof(ent) != DC_WALL_SHUNT_VT_PTR)
    {
        ent = getlocalvar("self");
    }

    // Get anchor location.
    x		= getentityproperty(ent, "x");
    y		= getentityproperty(ent, "y");
    z		= getentityproperty(ent, "z");

    // Get initial check location.
    check_x = getentityproperty(bound, "x");
    check_z = getentityproperty(bound, "z");
    anchor_b = getentityproperty(bound, "base");

    // Bound is right of anchor?
    if (check_x > x)
    {
        // Check wall and hole using temporary checklocation w/adjustment.
        // If in a wall but not a pit, decrement the offset and location,
        // then check again. Continue until either in a pit or not in a wall.
        do
        {
            x--;
            check_x--;

            wall = (checkwall(check_x+DC_WALL_SHUNT_ADJUST, check_z) > anchor_b);
            hole = checkhole(check_x+DC_WALL_SHUNT_ADJUST, check_z);
        }
        while(wall || !hole);
    }
    else
    {
        do
        {
            x++;
            offset_x++;

            wall = (checkwall(check_x+DC_WALL_SHUNT_ADJUST, check_z) > anchor_b);
            hole = checkhole(check_x+DC_WALL_SHUNT_ADJUST, check_z);
        }
        while(wall || !hole);
    }

    // Apply final calculated location to anchor.
    changeentityproperty(ent, "position", x, z, y);					//Apply location to anchor.

}

Well, i have carefully read your answer and what it says in the script, but I do not understand exactly what values should be set in this part:

(void ent, void bound)


I could understand as used.
It would be something like this:

Code: 
anim grabbackward
	 fastattack 1
	 loop       0
	 offset     87 177
	 bbox	    0 0 0 0
	 delay      1
         attackone 0
	 jumpframe 	2 3.3 0
	 landframe	7
	 sound      data/chars/raiden/rthrow.wav
	 frame	    data/chars/raiden/grab.png
        @cmd    slamstart
	 delay      35
        @cmd    antiwall -35 10 -1 
        @cmd    position 8 60 15 -1 1
	 frame	    data/chars/raiden/throw00.png
	 delay      30
	 offset     109 183
        @cmd    position 8 40 20 1 1
         frame      data/chars/raiden/throw01.png
	 delay      4
        @cmd    antiwall -35 10 -1 
        @cmd    position 10 25 20 1 1
         frame      data/chars/raiden/throw02.png
	 delay      1
         frame      data/chars/raiden/throw02.png
	 sound      data/sounds/punch.wav
        @cmd    antiwall -35 15 -1 
        @cmd    position 10 -30 -15 1 1
	 delay      2
         frame      data/chars/raiden/throw03.png
        @cmd    depost 0
        @cmd    throw 25 4 -4.5 -1.8 0 0
        @cmd dc_wall_shunt ? ?
	 delay      999
         frame      data/chars/raiden/throw03.png
         flipframe  7
	 delay      15
  	 offset	    92 177
	 frame	    data/chars/raiden/u1.png

Ent and bound are the holding entity and the defending (grappled) entities respectively. You call it this function immediately before releasing a bind, and it will ensure you don't leave the grappled entity inside of a wall. It replaces your antiwall function and only needs to be called that one time.

OpenBor crash with this script.

First... The engine detected an error and shut itself down, it did not crash. There is a big difference and it does matter. Second, you removed the constants definition when you copied, so of course it won't work.
