Force Grip (New Grip) and Force Choke (Old Grip)

[JediBantha]

After many tries, I finally got this one to work, except that it does the same thing as the old Grip whenever I set it to anything other than zero.

 

#define BUTTON_FORCEGRIP 64

#define BUTTON_FORCEGRASP 64

 

Is there anything I can do to fix this?

[Raz0r]

The buttons are stored in a bit-field. 64 is the 7th bit (represented as "0100 0000", or 64)

In base, there are 12 buttons being used, so you'll have to make your new force-power be the 13th button, i.e. the 13 bit (represented as "0001 0000 0000 0000", or 4096)

You can then access it via /bind x +button12

[JediBantha]

So if I were to make a 14th button, would I have to do 1 * 2 * 2 * 2 (and so forth) to get the proper value for it, and type that number in?

[Raz0r]

Yep. You can double the previous value.

You can only have up to 15 buttons in Raven's jamp.exe, and 16 in OpenJK without engine modifications.

Also, I'm trying to figure out how to loop the "BOTH_PULLED_INAIR_F" and "BOTH_PULLED_INAIR_B" anims for the new grip. Every time I lift someone up, the anim always freezes at it's last frame.

 

I recall a mod called "Telekinesis" on JK3Files, which replaced the choke anim for the old grip, but I've never swapped anims myself.

[eezstreet]

To make the animations loop, I believe that's part of the animations.cfg that needs to be edited. I don't remember which part in particular.

[Circa]

It's the second to last number of the line. Make it zero to loop.

The quick explanation of what Circa is showing you is:

Animation name, the the starting frame of the animation, the number of frames in the animation, wheiter it plays once (-1) or loops (0), and the speed (normally 20 or 40)

[Archangel35757]

But if the animation was not designed to loop (last frame blending back to first frame) then it will probably have a noticeable glitch as it loops.

[eezstreet]

Those two are meant to loop, I believe.

Indeed it will.

'Kay, now how do I make it so Grip can now lift objects?

[Raz0r]

game/w_force.c

void ForceGrip( gentity_t *self )

Look for checks like:

	if ( !WP_ForcePowerUsable( self, FP_GRIP ) )

	if ( tr.fraction != 1.0 &&
		tr.entityNum != ENTITYNUM_NONE &&
		g_entities[tr.entityNum].client && // <---- HERE
		!g_entities[tr.entityNum].client->ps.fd.forceGripCripple &&
		g_entities[tr.entityNum].client->ps.fd.forceGripBeingGripped < level.time &&
		ForcePowerUsableOn(self, &g_entities[tr.entityNum], FP_GRIP) &&  // <---- HERE
		(g_friendlyFire.integer || !OnSameTeam(self, &g_entities[tr.entityNum])) ) //don't grip someone who's still crippled

Modifying those checks to allow non-client entities should work.

There might be other places in code that rely on the gripped object being a client. I'm not sure.

[JediBantha]

What about the SP version of grip?

[Raz0r]

Ah, not sure. It's probably very similar.

[ChalklYne]

This thread has peaked my interest. I have been asking for years how hard it would be to grip more than one person at a time depending on if they were in a certain proximity of each other.

[JediBantha]

I suppose you could grip multiple people if you hold down the "Use" button before gripping, like TFU1.

 

EDIT: Btw, it's different from the SP Grip; different lines of coding.
