thx for clearing that up

Wrong

At jump off, engine always use constant gravity without any pev_gravity modifers... It`s easily proof with setting sv_gravity to 0, so if sqrt(2 * 0 * 56.0) = 0 - we never jump with such method... And it`s not true.

Default value must be constant from sqrt(2 * 800 * 56.0).

Next frame velocity[2] we can calculate as: next_vel[2] = velocity[2]-pev_gravity*sv_gravity*UC_msec*0.001. But jump_off velocity without modifers...
Also anyone tested it to proper engine emulation (correct jump height - 56 by default)?

Conner I think you need an IN_FORWARD check. if I remember right you should not be able longjump when going backward, etc...

[ConnorMcLeod]

I think you are able, but that whatever the direction you go, the longjump makes you go forward, may be it's not logic, but it's coded like that :/

even so I still believe it wasn't possible to longjump without IN_FORWARD... meaning if you are moving backward you can't longjump, if your momentum was moving forward without holding IN_FORWARD you can't longjump. Not talking about the direction of the jump itself, that I know goes forward and does so correctly here.

I know you realize what I meant in the first post, just clarifying for others.

Just have a look by yourself to PM_Jump :

There is just a check on duck + jump and min velocity.

void PM_Jump (void)
{
[...]
// See if user can super long jump?
	cansuperjump = atoi( pmove->PM_Info_ValueForKey( pmove->physinfo, "slj" ) ) == 1 ? true : false;

	// Acclerate upward
	// If we are ducking...
	if ( ( pmove->bInDuck ) || ( pmove->flags & FL_DUCKING ) )
	{
		// Adjust for super long jump module
		// UNDONE -- note this should be based on forward angles, not current velocity.
		if ( cansuperjump &&
			( pmove->cmd.buttons & IN_DUCK ) &&
			( pmove->flDuckTime > 0 ) &&
			Length( pmove->velocity ) > 50 )
		{
			pmove->punchangle[0] = -5;

			for (i =0; i < 2; i++)
			{
				pmove->velocity[i] = pmove->forward[i] * PLAYER_LONGJUMP_SPEED * 1.6;
			}
		
			pmove->velocity[2] = sqrt(2 * 800 * 56.0);
		}
		else
		{
			pmove->velocity[2] = sqrt(2 * 800 * 45.0);
		}
	}
	else
	{
		pmove->velocity[2] = sqrt(2 * 800 * 45.0);
	}

	// Decay it for simulation
	PM_FixupGravityVelocity();

	// Flag that we jumped.
	pmove->oldbuttons |= IN_JUMP;	// don't jump again until released

[creeperdank]

So witch one do i dl?
The first or the second post?

[Arkshine]

The second uses Orpheu, it's a more efficient version.

[creeperdank]

Off topic but what is Orpheu?
I haven't used amxx in a while.

[Arkshine]

It's a new and extremely powerful module for Amxx. Follow the link in my post and read.
