Hi everyone,
I’m following a UE5 enemy AI tutorial, but I’ve run into a movement issue that I can’t figure out.
The zombie successfully follows the player using AI Move To, but every few seconds it briefly slows/stutters and then catches back up before continuing to chase. It repeats this behaviour continuously.
The walk animation never stops playing—it appears to be the movement itself that hesitates rather than the animation.
AI Setup
- BP_Zombie inherits from Character
- Uses AI Move To to chase the player
- Character Movement component
- NavMeshBoundsVolume covering the level
- AI Controller assigned
- Animation Blueprint with Idle/Walk state machine
- Movement speed driven from Get Velocity → Vector Length
Things I’ve already tested
- Increased Acceptance Radius
- Removed the delay between AI Move To calls
- Verified the Animation Blueprint is working correctly
- Verified the walk animation never stops
- Rotation towards the player is smooth
- AI Move To only reports Success when the enemy reaches the player
- Character Movement Max Walk Speed appears normal
- The instructor’s project moves smoothly while mine does not
I will also post a video of the problem im having: https://youtu.be/xGo4DaHAUCQ
heres is my enemy AI Character BP:
My enenmy Ai character movement details:
I’ve also checked the Animation Blueprint, acceptance radius, delay timings, and Character Movement speed.
Please can anyone help fix the enemy ai stuttering/lag issue?
