Question in the title ^.^

I've already tried blocking the buttons themselves, but it still gets through.

[KawMAN]

Try this:

PHP Code:

public Action:OnPlayerRunCmd(client, &buttons, &impulse, Float:vel[3], Float:angles[3], &weapon)
{
    if(buttons & IN_JUMP)
    {
        buttons &= ~IN_JUMP;
    }
    if(buttons & IN_DUCK)
    {
        buttons &= ~IN_DUCK;
    }
    return Plugin_Continue;
}

I'm guessing that's what you meant by blocking the buttons?

The fact that it "gets through" is because of the prethinking.
The client expects to be able to crouch/jump, so it'll show the client as if he's jumping before the server's got time to respond.

Can't do much about that. Last topic about it got to a dead end.

You could disable fall damage and set the client's gravity to an obscene amount, that would at least prevent jumping.

Getting a bit ridiculous with this suggestion but it might be fun to try

Increase player gravity like the twistedpanda said, then turn down LaggedMovementValue to something that will counter-balance fall speed. LMV will slow a player down and their fall speed as well. Then to counter-balance that, use SDKHooks and PrePostThink to increase the player's speed.

Theoretically you will have a client that can't jump higher than a milimeter but everything else should be the same. If you wanna try this then say so and I'll give more info on using PrePostThink to set speed.

[almcaeobtac]

It's worth a shot

Also, what's the difference between the movetypes: MOVETYPE_ISOMETRIC and MOVETYPE_WALK?

[blodia]

MOVETYPE_ISOMETRIC ignores all player speed formatting so players will move at sv_maxpeed or the cl_ speed limiting cvars whichever is lower.

m_flGravity isn't networked, so it will mess client predictions as well. If you really wanna alter the gravity, I'd suggest using it in combination with SendConVarValue and lie to the client that sv_gravity was changed to match his gravity.

Here's something from the source sdk in case you don't like that solution. Its probably not exactly the same as the one in whatever mod you're doing this for, but should be pretty close anyhow.

PHP Code:

bool CGameMovement::CheckJumpButton( void )
{
    if (player->pl.deadflag)
    {
        mv->m_nOldButtons |= IN_JUMP ;    // don't jump again until released
        return false;
    }

    // See if we are waterjumping.  If so, decrement count and return.
    if (player->m_flWaterJumpTime)
    {
        player->m_flWaterJumpTime -= gpGlobals->frametime;
        if (player->m_flWaterJumpTime < 0)
            player->m_flWaterJumpTime = 0;
        
        return false;
    }

    // If we are in the water most of the way...
    if ( player->GetWaterLevel() >= 2 )
    {    
        // swimming, not jumping
        SetGroundEntity( (CBaseEntity *)NULL );

        if(player->GetWaterType() == CONTENTS_WATER)    // We move up a certain amount
            mv->m_vecVelocity[2] = 100;
        else if (player->GetWaterType() == CONTENTS_SLIME)
            mv->m_vecVelocity[2] = 80;
        
        // play swiming sound
        if ( player->m_flSwimSoundTime <= 0 )
        {
            // Don't play sound again for 1 second
            player->m_flSwimSoundTime = 1000;
            PlaySwimSound();
        }

        return false;
    }

    // No more effect
     if (player->GetGroundEntity() == NULL)
    {
        mv->m_nOldButtons |= IN_JUMP;
        return false;        // in air, so no effect
    }

    // Don't allow jumping when the player is in a stasis field.
#ifndef HL2_EPISODIC
    if ( player->m_Local.m_bSlowMovement )
        return false;
#endif

    if ( mv->m_nOldButtons & IN_JUMP )
        return false;        // don't pogo stick

    // Cannot jump will in the unduck transition.
    if ( player->m_Local.m_bDucking && (  player->GetFlags() & FL_DUCKING ) )
        return false;

    // Still updating the eye position.
    if ( player->m_Local.m_flDuckJumpTime > 0.0f )
        return false;


    // In the air now.
    SetGroundEntity( (CBaseEntity *)NULL );
    //irrelevant code omitted
} 


There we have a bunch of conditions that are checked before a client is allowed to jump. Make sure one of them fails (on client side too) and you're good to go! I just tested setting deadflag to true and it worked very nicely, but I'm unsure if it has any side effects... feel free to experiment!

its probably safer the make the game think the player is already in the air

PHP Code:

SetEntPropEnt(client, Prop_Send, "m_hGroundEntity", -1);

That will probably have undesired side-effects because of the way velocity is processed in the Source engine.
