wall jump question.

DD Tokki · Mar 19, 2023

I'm considering wall jumping for the enemy's movement.
When you jump normally, it doesn't bounce and comes right down.
I would like to create a scene where I bounce off the wall in the opposite direction when I make a special jump (freespecial).

Hi @DD Tokki

Here's an example of the script I'm using on SORX to allow Blaze/Sammy/Shiva to jump walls. You need to create a onblockw.c event file, put this code inside and call the onblockwscript event on every character that can jump walls.

C:

onblockwscript        data/scripts/onblockw/default.c

This event happens every time a character is blocked by walls (the same goes for onblocks.c file too, which refers to the screen edge).

C:

void main()
{//Make characters jump in walls
    
    void self        = getlocalvar("self");
    void ani        = getentityproperty(self, "animationID");
    int iPIndex        = getentityproperty(self, "playerindex");
    float pause        = 30;

    if(ani == openborconstant("ANI_JUMP")){
        float xVel = 2;
        float yVel = 1;
        
        if(playerkeys(iPIndex, 0, "moveleft")){
            changeentityproperty(self, "direction", 0);
            xVel = -xVel;
        }
        else
        if(playerkeys(iPIndex, 0, "moveright")){
            changeentityproperty(self, "direction", 1);
        }
        else
        {
            xVel = 0;
        }
        
        if(playerkeys(iPIndex, 1, "jump")){
            changeentityproperty(self, "animation", openborconstant("ANI_WALKOFF"));
            changeentityproperty(self, "aiflag", "frozen", 1);
            changeentityproperty(self, "freezetime", openborvariant("elapsed_time")+pause);
            tossentity(self, yVel, xVel, 0);
        }
    }
}

thank you
But it seems different from what I want.
Blaze feels like double-jumping off a wall, but I
I want the feeling of a ball bouncing off a wall like in a script like wallbons.c.

[SCRIPT] Wall Jump without animationscript

Wall Jump without animationscript Author: O Ilusionista Version: V2 - 2019.01.26 Thanks: Bloodbane and Damon Caskey. I've made an alternative way to use Wall Jump. Following a tip by DC, I decided to use another way to make this. OpenBOR already does a great job detecting when you are blocked...

You can freely edit the properties to act like wall bouncing using the previous script, but SORX has wall bouncing script too, like this:

C:

void main()
{//Simulate hitwall effect when thrown or being hit by certain attacks (ALL THROWS/SLAMS AND BOWLING SKILLS, BARBON/ADAM)
    void self       = getlocalvar("self");
    void anim       = getentityproperty(self, "animationID");
    int dead        = getentityproperty(self, "dead");
    int limit       = 20;
    float height    = getentityproperty(self, "y");
    float xDir      = getentityproperty(self, "xdir");
    float mult      = 1.1;
    
    if(!dead){
        if( anim == openborconstant("ANI_FALL")     ||
            anim == openborconstant("ANI_BURN")     ||
            anim == openborconstant("ANI_SHOCK")    ||
            anim == openborconstant("ANI_FALL8")    ||
            anim == openborconstant("ANI_FALL9")    ){
            if(height >= limit){
                spawn01("Flash", 0, 50, 1);
                spawn01("QuakeLow", 0, 0, 0);
                sound("sor3_hit6.wav");
                tossentity(self, NULL(), -xDir/mult, 0);
            }
        }
    }
}

do you want this effect

Those videos are set "Private". Put to "Unlisted".

Is this script also applied as onblockwscript ? I'm asking because the game doesn't run.

That's right. It is the action of bouncing against the wall.

pudu · Mar 19, 2023

onblockwscript data/scripts/bounce.c //touch the wall to execute
onblocksscript data/scripts/bounce.c//Touch the edge of the screen to execute

Code:

void main()
{//screen edge and wall, bounce
    void self = getlocalvar("self");
    void Dir = getentityproperty(self, "direction");
    void vAniID = getentityproperty(self,"animationID");
    int iPIndex = getentityproperty(self,"playerindex");
    void iJump = playerkeys(iPIndex, 1, "jump");
    int y = getentityproperty(self, "a");
    int b = getentityproperty(self, "base");

      if(vAniID == openborconstant("ANI_JUMP")){
        if(iJump && y > b+1 && Dir == 1){
          changeentityproperty(self, "direction", 0);
          changeentityproperty(self, "animation", openborconstant("ANI_FOLLOW15"));
        }else if(iJump && y > b+1 && Dir == 0){
          changeentityproperty(self, "direction", 1);
          changeentityproperty(self, "animation", openborconstant("ANI_FOLLOW15"));
    }
  }
}

Code:

anim follow15
        loop    0
    delay    25
    offset    72 131
    bbox    64 102 16 15

     landframe  5

    delay    1
        frame   data/chars/mboss05/0a503.gif

Code:

void toss0001(int iSTime)
{
    /*

    Damon Vaughn Caskey

    Adds tosstime to caller.

    void vSelf = getlocalvar("self");  
    int  iTime = openborvariant("elapsed_time");

    changeentityproperty(vSelf, "tosstime", iTime + iSTime);
}

You need to remove the lines you will not use, mainly the sound and spawn01 functions, because I pasted directly from SORX.

thank you This seems to be applied to the fall animation, but can I change it to jump or freespecial only?

Yes, you can use the script in any animation. But after looking at Pudu's example, I think the first method works better and you can remove the double jump effect by doing adjustments on the velocities applied or removing the freeze effect.

Now I know what kind of function pudu's script is.
Here, if the wall jump of bounce script is combined with hitwall.c property, it seems to be the function I want.

This is a useful feature for players.
Since it is applied to Enemy, I would like button input on the wall to be automatic.

You can delete the iJump related code so that the sprite will bounce automatically if it hits a wall or the edge of the screen after jumping

maxman · Mar 21, 2023

Here is what pudu means by removing this iJump.

C:

void main()
{//screen edge and wall, bounce
    void self = getlocalvar("self");
    void Dir = getentityproperty(self, "direction");
    void vAniID = getentityproperty(self,"animationID");
    //int iPIndex = getentityproperty(self,"playerindex");
    //void iJump = playerkeys(iPIndex, 1, "jump");
    int y = getentityproperty(self, "a");
    int b = getentityproperty(self, "base");

      if(vAniID == openborconstant("ANI_JUMP")){
        if(y > b+1 && Dir == 1){
          changeentityproperty(self, "direction", 0);
          changeentityproperty(self, "animation", openborconstant("ANI_FOLLOW15"));
        }else if(y > b+1 && Dir == 0){
          changeentityproperty(self, "direction", 1);
          changeentityproperty(self, "animation", openborconstant("ANI_FOLLOW15"));
    }
  }
}

pudu, I apologize and I didn't mean to have a mean tone on you. I was only letting you know.
