Remove Bunny Hop From Single Player RTCW

(wolfETplayer) #1

I want to remove bunny hop(jump acceleration) from single player RTCW. I know there is some restriction on bunny hop and strafe jumping in RTCW MP. I’m working with source code, however i couldn’t find the way Nerve did that.

All that i found is PM_Checkjump in bg_pmove.c:

=============
PM_CheckJump

*/
static qboolean PM_CheckJump( void ) {
// JPW NERVE – jumping in multiplayer uses and requires sprint juice (to prevent turbo skating, sprint + jumps)
// don’t allow jump accel
// if (pm->cmd.serverTime - pm->ps->jumpTime < 850)

if ( pm->cmd.serverTime - pm->ps->jumpTime < 500 ) { // (SA) trying shorter time. I find this effect annoying :wink:
return qfalse;
}

if ( pm->ps->pm_flags & PMF_RESPAWNED ) {
return qfalse; // don’t allow jump until all buttons are up
}

if ( pm->cmd.upmove < 10 ) {
// not holding jump
return qfalse;
}

// must wait for jump to be released
if ( pm->ps->pm_flags & PMF_JUMP_HELD ) {
// clear upmove so cmdscale doesn’t lower running speed
pm->cmd.upmove = 0;
return qfalse;
}

pml.groundPlane = qfalse; // jumping away
pml.walking = qfalse;
pm->ps->pm_flags |= PMF_JUMP_HELD;

pm->ps->groundEntityNum = ENTITYNUM_NONE;
pm->ps->velocity[2] = JUMP_VELOCITY;
PM_AddEvent( EV_JUMP );

if ( pm->cmd.forwardmove >= 0 ) {
BG_AnimScriptEvent( pm->ps, ANIM_ET_JUMP, qfalse, qtrue );
pm->ps->pm_flags &= ~PMF_BACKWARDS_JUMP;
} else {
BG_AnimScriptEvent( pm->ps, ANIM_ET_JUMPBK, qfalse, qtrue );
pm->ps->pm_flags |= PMF_BACKWARDS_JUMP;
}

return qtrue;
}

I think this is the right thing. However I can’t find a way to make this work in single player. Maybe someone on this forums can help me out with this?

Hello, WolfETPlayer. Why would you want to remove the iconic “bunny hopping” feature from Rtcw SP? Quite a few players use this feature, and it makes Rtcw unique, since most games don’t have this.

I can’t help you out though, because I know nothing regarding editing the source code. :frowning:

id Software left it in because removing the engine glitch was too difficult, good luck with your efforts

Well, somehow Nerve Software managed to restrict bunny hop in RTCW multiplayer. I hope to do the same in single player.

Thanks to Eugeny I figured it out. You just need to change this:

if ( pm->cmd.serverTime - pm->ps->jumpTime < 500 )

to this

if ( pm->cmd.serverTime - pm->ps->jumpTime < 850 )

Eugeny is highly skilled with the Rtcw source code. We are lucky to have him, and congratulations on solving your problem WolfETPlayer. :slight_smile:
