Jump from walls / edges

NED · Apr 19, 2014

Basically, I'm trying to understand how to do triangle jump (Chun Li wall jump move) But with an automatic move done like triangle jump kick...

I would like it to be possible on screen edge, walls and vertical surface of obstacles and platforms.

I've seen in the BK chinese mod I won't name here...

Is there a way to use this feature?
Thanks

Here my key.c

Code:

void main()
{
//	int iPlIndex = 0; //Player index.
	int iPlIndex = getlocalvar("self"); //Get calling player
//	int iPlIndex = getentityproperty(self,"playerindex"); //Get player index
    void vSelf = getplayerproperty(iPlIndex , "entity"); //Get calling entity
    void vAniID = getentityproperty(vSelf,"animationID"); //Get current animation ID
    void vAniPos = getentityproperty(vSelf, "animpos"); //Get current animation frame
    int iDir = getentityproperty(vSelf, "direction");  //Get current facing direction
	int x = getentityproperty(vSelf, "x");	// Get x pos
    int y = getentityproperty(vSelf, "a");	// Get y pos
    int z = getentityproperty(vSelf, "z");	// Get z pos

    void iUp = playerkeys(iPlIndex, 1, "moveup"); // New key status of "Up"
    void iDown = playerkeys(iPlIndex, 1, "movedown"); // New key status of "Down"
    void iLeft = playerkeys(iPlIndex, 1, "moveleft"); // New key status of "Left"
    void iRight = playerkeys(iPlIndex, 1, "moveright"); // New key status of "Right"
    void iJump = playerkeys(iPlIndex, 1, "jump"); //New key status of "Jump"
    void iSpecial = playerkeys(iPlIndex, 1, "Special"); //New key status of "Special"

    void iAttack3 = playerkeys(iPlIndex, 1, "attack3"); // New key status of "Attack 3"
    void iAttack4 = playerkeys(iPlIndex, 1, "attack4"); // New key status of "Attack 4"

	void iUpR = playerkeys(iPlIndex, 2, "moveup"); // Release status of "moveup"
	void iDownR = playerkeys(iPlIndex, 2, "movedown"); // Release status of "movedown"
    void iLeftR = playerkeys(iPlIndex, 2, "moveleft"); // Release status of "Left"
    void iRightR = playerkeys(iPlIndex, 2, "moveright"); // Release status of "Right"
	void iJumpR = playerkeys(iPlIndex, 2, "jump"); // Release status of "Jump"
	void iSpecialR = playerkeys(iPlIndex, 2, "Special"); // Release status of "Special"
	void iAttackR = playerkeys(iPlIndex, 2, "attack"); //Release status of "Attack"
	void iAttack2R = playerkeys(iPlIndex, 2, "attack2"); // Release status of "Attack 2"
	void iAttack3R = playerkeys(iPlIndex, 2, "attack3"); // Release status of "Attack 3"
	void iAttack4R = playerkeys(iPlIndex, 2, "attack4"); // Release status of "Attack 4"

	if(vAniID == openborconstant("ANI_JUMP") || vAniID == openborconstant("ANI_FORWARDJUMP") || vAniID == openborconstant("ANI_RUNJUMP") || vAniID == openborconstant("ANI_FOLLOW16"))
	{ //Jumping?	
		if (iJump)
		{ //New jump key press?
			if(iDir == 1 && y <= checkwall(x+5,z))
			{ // There is a wall
				changeentityproperty(vSelf, "direction", 0); 
				// Change to left facing
				changeentityproperty(vSelf, "velocity", 0, 0, 0); 
				// Set velocity
				changeentityproperty(vSelf, "animation", openborconstant("ANI_FOLLOW16"));
				// Switch to wall jump anim
			}
			else if(iDir == 0 && y <= checkwall(x-5,z))
			{ // There is a wall
				changeentityproperty(vSelf, "direction", 1);
				// Change to left facing
				changeentityproperty(vSelf, "velocity", 0, 0, 0);
				// Set velocity
				changeentityproperty(vSelf, "animation", openborconstant("ANI_FOLLOW16"));
				// Switch to wall jump anim
			}
			else if(y > checkwall(x-5,z) || checkwall(x-5,z))
			{ // There is no wall
				changeentityproperty(vSelf, "animation", openborconstant("ANI_FOLLOW4"));
				// Switch to double jump anim
			}
		}	
	}

Then on the player anim:

Code:

#-------WALL JUMP
anim	follow16
	delay	9
	offset	74 123
	bbox	67 67 25 22
		frame	data/chars/shinobi/193.png

	delay	35
	bbox	67 63 17 61
	sound	data/chars/shinobi/jump.wav

	delay	8
		frame	data/chars/shinobi/191.png
	bbox	67 71 17 50
		frame	data/chars/shinobi/192.png

I test it and works.

Well, I just set keyscript like above in player's text.
The script I posted in previous page doesn't change animation. The only change you can see is that when player bounces wall or screen edge, he/she will jump again still playing JUMP or FORWARDJUMP animation

Oh yes, in Avengers demo I noticed that players can move and flip while jumping. If you hold say right button while trying to bounce off rightscreen edge, it will appear that player isn't bouncing but the truth is holding button moves player to right after the bounce making it as if screen edge bounce isn't performed
That's what happened in my first test before I figured out the cause

ahhhhhh so maybe its the reason, let me check it out.

edit: I changed the jumpmove to this:

jumpmove 0 2

~~But the code isn't working yet.~~
Wait, I am stupid and forgot to press J again, lol

O Ilusionista · Sep 15, 2014

I am using Goliath's version (both both works) so I can use a new animation.

edit: I got it working the way I wanted:

I'm looking for the script to make enemies bounce off the screen edge when they're in fall animation. Does anyone have this?

Cheers

jonsilva · Jun 13, 2015

ive made this one only for when the entity dies
but iam using it on the entity header
it will pull the entity inside the screen even if he is 1000 pixel away
you can remove the hp <=0 && lines to make it always work

script @script
void main()
{
void self = getlocalvar("self");
int x = getentityproperty(self, "x");
int XPos = openborvariant("xpos");
int Screen = openborvariant("hResolution");
int hp = getentityproperty(self, "health");
void anim = getentityproperty(self,"animationID");

if(anim != openborconstant("ANI_DIE")){

if( hp <=0 && x >= XPos+Screen-60) // right
{
tossentity(self, 1, -2, 0);
}
else if( hp <=0 && x <= XPos+60) // left
{
tossentity(self, 1, 2, 0);
}
}
}
@end_script

O Ilusionista · Jun 13, 2015

bounce or rebound from the screen? You mean like a ball hitting a wall and boucing?
This code can do it.

NED · Jun 13, 2015

I think a combination of elements from these 2 scripts should do it :
-This wall and edge script
-Magggas's wall bounce script

I might be intersted on this one to for some specific game modes

aL BeasTie · Jun 13, 2015

I got it working with jonsilva's post. i just edited to only work when enemy is playing ANIM_FALL and changed the values to suit my screen size.

Bloodbane · Jun 14, 2015

...changed the values to suit my screen size

You don't need to do that, this line

Code:

   int Screen = openborvariant("hResolution");

already acquire your screen size

aL BeasTie · Jun 14, 2015

I meant I had to lower the +60/-60 values to +10/-10 or it didn't look right.

Code:

   if( hp <=0 && x >= XPos+Screen-60) // right
      {
   tossentity(self, 1, -2, 0);
      }
   else if( hp <=0 && x <= XPos+60) // left
      {
   tossentity(self, 1, 2, 0);
      }
  }
}

Any news on how to include platforms as well?

Wall jump requires keyscript like this:

walljump.c

void main()
{
int iPlIndex = getlocalvar("player"); //Get calling player
void vSelf = getplayerproperty(iPlIndex , "entity"); //Get calling entity
void vAniID = getentityproperty(vSelf,"animationID"); //Get current animation ID

int x = getentityproperty(vSelf, "x");
int y = getentityproperty(vSelf, "a");
int z = getentityproperty(vSelf, "z");

void iUp = playerkeys(iPlIndex, 1, "moveup"); // New key status of "Up"
void iDown = playerkeys(iPlIndex, 1, "movedown"); // New key status of "Down"
void iLeft = playerkeys(iPlIndex, 1, "moveleft"); // New key status of "Left"

void iSpecial = playerkeys(iPlIndex, 1, "Special"); //New key status of "Special"
void iAttack = playerkeys(iPlIndex, 1, "attack"); //New key status of "Attack"
void iAttack2 = playerkeys(iPlIndex, 1, "attack2"); // New key of "Attack 2"
void iAttack3 = playerkeys(iPlIndex, 1, "attack3"); // New key of "Attack 3"

if(vAniID == openborconstant("ANI_JUMP")){
if(iJump && iDir == 1 && y <= checkwall(x+15,z)){
changeentityproperty(vSelf, "direction", 0);
tossentity(vSelf, 3, -1, 0); // Wall Jump
} else if(iJump && iDir == 0 && y <= checkwall(x-15,z)){
changeentityproperty(vSelf, "direction", 1);
tossentity(vSelf, 3, 1, 0); // Wall Jump
}
}
}

Click to expand...

Copy this in a file name walljump.c, save it in data/scripts folder then declare it like this:

keyscript data/scripts/walljump.c

To perform wall jump, simply jump against a wall then press jump when character is blocked by wall. The character will change direction, jumps higher WITHOUT changing animation

HTH

Got this working with normal and forward jumps, no problems.

-How to make it change to another animation? like for example, I want my characters to jump again, but i have this wallbounce sprite i want to put when this happens.

-How to make it work just at the the peak of the jump instead being able to walljump even if i'm already going down and at a very low altitude?

-How to make it change to another animation? like for example, I want my characters to jump again, but i have this wallbounce sprite i want to put when this happens.

Simply change this part :

Code:

    if(vAniID == openborconstant("ANI_JUMP")){
     if(iJump && iDir == 1 && y <= checkwall(x+15,z)){
        changeentityproperty(vSelf, "direction", 0);
        tossentity(vSelf, 3, -1, 0); // Wall Jump
      } else if(iJump && iDir == 0 && y <= checkwall(x-15,z)){
        changeentityproperty(vSelf, "direction", 1);
        tossentity(vSelf, 3, 1, 0); // Wall Jump
      }
    }

to this:

Code:

    if(vAniID == openborconstant("ANI_JUMP")){
     if(iJump && iDir == 1 && y <= checkwall(x+15,z)){
        changeentityproperty(vSelf, "direction", 0);
        changeentityproperty(vSelf, "animation", openborconstant("ANI_FOLLOW3"));
      } else if(iJump && iDir == 0 && y <= checkwall(x-15,z)){
        changeentityproperty(vSelf, "direction", 1);
        changeentityproperty(vSelf, "animation", openborconstant("ANI_FOLLOW3"));
      }
    }

The 2nd code changes animation to FOLLOW3 when wall jump is performed
Note : I removed tossentity function cause I assume the jumping will be set in FOLLOW3 animation. Also since player is still in jumping state, when FOLLOW3 is played, player still have jumping momentum IOW not stopping and might fall

-How to make it work just at the the peak of the jump instead being able to walljump even if i'm already going down and at a very low altitude?

If walljump is excluded, it should be simple but if it is, then it's rather complex

As O'Ilusionista request this is my hold wall jump.
Assume that you JUMP animation is FOLLOW45:
