Original report: https://github.com/chromiecraft/chromiecraft/issues/750

CURRENT BEHAVIOUR:

I was fishing off the coast of Tanaris (near Steamwheedle Port, at 64.6 ; 24.6) and a Steeljaw Snapper started jumping. Seems like an issue with water/terrain? Here is a video: https://youtu.be/Os8JN2G27Mg

EXPECTED BLIZZLIKE BEHAVIOUR:

The turtle should be swimming or walking, not jumping up and down.

SOURCE:

STEPS TO REPRODUCE THE PROBLEM:

1. Go to 67.4 ; 24.6 in Tanaris, wait a moment till the Steeljaw Snapper jumps.

EXTRA NOTES:

N/A.

@UltraNix Do you know if this is related to Vmaps? Could it be that the the Turtle size and the shallow water is trying to place it in ground but fails a check?

[T1ti]

I see similar stuff happen even without water, I think that's when the client map deosn't match the virtual map/ the creature being sent a coordinate from the server that deosn't match the physical map, it keeps visually jumping becasue the client physics deosn't match

make a creature path in air or climb a mountain and it will do shit like that

[T1ti]

I saw yesterday a core hound in molten core do that on the thin bridge, specifically

[ghost]

More vmaps issues then

[UltraNix]

No - it's not a problem with vmaps. Check if this creature have UNIT_FLAG_SWIMMING or/and Inhabit_water in its creature_template entry.

[ghost]

Yes, they have both UNIT_FLAG_SWIMMING and the correct Inhabit_water both water and ground.

This should be the correct behaviour when swapping form one inhabit type to the other: https://www.youtube.com/watch?v=VlapUuuyVy4&ab_channel=AYeeAYee
