Make MU Alive Again — Let’s Share Our Fixes Together!
Here is a contribution from me: a set of fixes for custom pet following behavior and wall-clipping issues.
✔ Fix 1:
When a Dark Lord is wearing Dark Spirit, custom pets were not following the character. This has now been corrected.
✔ Fix 2:
Custom pets sometimes clip through walls or terrain on certain maps. This issue has been fixed as well.
✔ Additional Improvement
I also added proper follow animations for custom pets depending on the character’s state —
whether the player is standing still or moving, the pet now plays the correct animation while following.
Hopefully this helps other developers.
Let’s continue sharing and improving MU together!
