Hello,

I hope I can get some ideas how to script knockback.

Knockback itself isn't such a problem, but checking players not to fall through walls/impassable tiles is something that I currently cannot think of any solution.

Is there any hardcoded check for this or can anyone point me in right direction?

you can try canmove function:

if <canmove n>
say i can move to north
endif

This is my server's "Knockback" enchantment, written by EXTREME. It works pretty well. Wink

There's 3 levels, Minor, Moderate and Major. All it really does is raise the chance to knockback.

It's designed to be applied to a weapon, so if you just want to apply it to a monster/NPC directly, simplypull the ON=@DAMAGE portion out of the TYPEDEF and stick it on the monster/NPC or it's EVENTS script. Smile

Code:

[TYPEDEF E_WEAPON_ENCHANT_KNOCKBACK_MINOR]

ON=@DAMAGE

IF <R1,10> == 1

 SRC.KNOCKBACK <TOPOBJ.DIR>

 SRC.EFFECT 3,i_fx_glow_spike,1,17,0

 SRC.SOUND 314

ENDIF

[TYPEDEF E_WEAPON_ENCHANT_KNOCKBACK_MODERATE]

ON=@DAMAGE

IF <R1,5> == 1

 SRC.KNOCKBACK <TOPOBJ.DIR>

 SRC.EFFECT 3,i_fx_glow_spike,1,17,0

 SRC.SOUND 314

ENDIF

[TYPEDEF E_WEAPON_ENCHANT_KNOCKBACK_MAJOR]

ON=@DAMAGE

IF <R1,2> == 1

 SRC.KNOCKBACK <TOPOBJ.DIR>

 SRC.EFFECT 3,i_fx_glow_spike,1,17,0

 SRC.SOUND 314

ENDIF

[FUNCTION KNOCKBACK]

IF <ARGS>

 LOCAL.DIR <EVAL <ARGS>+4>

 IF <dLOCAL.DIR> > 7

  LOCAL.DIR -= 8

 ENDIF

ELSE

 LOCAL.DIR <DIR>

ENDIF

DOSWITCH <dLOCAL.DIR>

 BEGIN

  IF (<CANMOVE S>)

   MOVE S

  ENDIF

 END

 BEGIN

  IF (<CANMOVE SW>)

   MOVE SW

  ENDIF

 END

 BEGIN

  IF (<CANMOVE W>)

   MOVE W

  ENDIF

 END

 BEGIN

  IF (<CANMOVE NW>)

   MOVE NW

  ENDIF

 END

 BEGIN

  IF (<CANMOVE N>)

   MOVE N

  ENDIF

 END

 BEGIN

  IF (<CANMOVE NE>)

   MOVE NE

  ENDIF

 END

 BEGIN

  IF (<CANMOVE E>)

   MOVE E

  ENDIF

 END

 BEGIN

  IF (<CANMOVE SE>)

   MOVE SE

  ENDIF

 END

 BEGIN

  IF (<CANMOVE S>)

   MOVE S

  ENDIF

 END

ENDDO

Thanks, rayvolution. Knockback works. But my character can be knocked through doors, walls and other impassable stuff.

Is anything set wrong in my sphere.ini or something?

Edit: My bad, for players with plevel 0 it works like a charm. Thanks a lot!

hehe, yeah, GMs totally ignore walls/non-passable objects. The only reason GMs even "stop" when they hit a wall is because the client says no, not the server. Tongue

So, in the case of GMs, they always pass the "Canmove" check no matter what. Wink
