Hi

currently I use this:

public BulletImpact(Handle:event, const char[] name, bool:dontBroadcast) {
        float bulletDestination[3];
        bulletDestination[0] = GetEventFloat(event, "x");
        bulletDestination[1] = GetEventFloat(event, "y");
        bulletDestination[2] = GetEventFloat(event, "z");
}

to get the Bullet Destination, but when I do a fast move while shooting, I get sometimes very wrong results.

Is there a better way doing this?

You can disable prediction:
sv_client_predict 0
Or you should use bonemerge with these offsets as shifts ( SetParentAttachmentMaintainOffset )... then it will be predicted with its parent

PHP Code:

    new enteffects = GetEntProp(ent, Prop_Send, "m_fEffects");
    enteffects |= EF_BONEMERGE;
    SetEntProp(ent, Prop_Send, "m_fEffects", enteffects); 


But it may not work (I mean SetParentAttachmentMaintainOffset)

I don't realy understand what you mean.

If I shift it, I need to know the Offset, but the Offset is always different, so I don't know it....

And I can't find anything helpfull about SetParentAttachmentMaintainOffset.

Ok, you know the real player position and the absolute position of BulletImpact. Just subtract one from the other and result will be the shift (offsets) that you are looking for. Than, as a player model is predictable, you should attach your "thing" to it and make it predictable with the player model.
Here is an example:

To make the entity predictable you should use EF_BONEMERGE flag, or this entity https://developer.valvesoftware.com/...namic_ornament
If you don't want to "display" something in the impact position, than you can just use the result of the BulletImpact function, as it returns the correct position (for the server)
The real position and visible position are highly depend on your ping. The server doesn't know predicted results, so you can't control it directly from the server.
If you want to use particle systems, then you should create a model with ones:

These are the only ways I know to make it to display correctly. You can also check this thread https://forums.alliedmods.net/showthread.php?t=261725 but I haven't find a way to make it "predictable"
Is the "Destination", you are talking about - another player ?
If it's not a secret, what do you want to achieve?

Thank you, for your reply.
I'm still not sure, what you mean.


Here is what I think:

If I shoot, the bullet hits on C, but sometimes I get the coordinates of B.
How does the real Player position help me when I want to get the offset?

Sorry, but I'm new to modding with sourcemod, so maybe I missunderstand you.



Edit: just saw your edit.
So you mean, that I get the real possition, but the client shows a wrong one?
I would like to create a trace, between the player and the bullet (where it hits the wall, a player or something else). I saw another plugin, where it was made with the player-look-direction, but this works only for weapons, which don't spray....

Well, I suppose it's not possible. Bullet impact sprite - is a client side thing, you don't see it the same way as the server does, because of the ping-time shift. The result, the server gives to you is correct, and the sprite position is incorrect because of the prediction. The only way to minimize the difference - is to try to recalculate the prediction shift. I think the shift should be close to 'your speed'*'your ping', but I may be wrong. You should also take into account the spread of the bullets hit and recoil, it depends on the speed and the type of the weapon.
Perhaps this article will help you https://developer.valvesoftware.com/wiki/Prediction

Ok, then I will let it like it is now. It's better than nothing.

Thank you for your help!
