I need help. I am writing a character movement script.

[XUEkfk]

This is a character movement script with states such as Idle, Walk, Dash, and Climb. However, the Climb script keeps having issues. Either the character can't climb up, or there are problems with climbing in other directions. The most critical issue is that when the character climbs to a certain height, it stops climbing but doesn't fall down. It just gets stuck in mid-air and, after some time, starts climbing again. I feel so helpless right now... the more I write, the less I know how to fix it...

Hi @XUEkfk,

I understand how frustrating it can be when things don’t work as expected. Based on your description, it sounds like the character is stuck in mid-air while climbing. Here are a few quick suggestions:

Climb Logic: Ensure transitions to states like Idle or Fall are working properly.
Physics & Collisions: Check collision layers or rigidbody settings for issues.
Debugging: Use logs to track the character’s position and state transitions.
Animation States: Confirm animations and transitions are set up correctly.
Coroutines: Review your coroutines to handle all state transitions.
Let me know if you need further assistance or want to share more details. You’ve got this!

Best regards,
Charles Norris

Thanks for your suggestion! It’s working properly now!!! I added a few checks to detect movements while climbing
