🖱️ Sprite won’t follow mouse pointer correctly
Hi everyone! I’m working on a project where I want my sprite to follow the mouse pointer, but something weird is happening. The sprite seems to move away from the mouse instead of following it properly.
I’ve tried different movement codes but the sprite behavior is still not right. Can someone help me figure out what’s going wrong? The sprite should smoothly follow the mouse cursor but it’s doing the opposite! 😅

Hey @SpriteHelper_2024! This is a very common issue that many beginners face. The problem is usually related to the sprite’s center point not being properly positioned. Here’s how to fix it:
🎯 Step 1: Fix the Sprite Center Point
The most common cause is that your sprite’s center point is not in the right place:
- Go to the Costumes tab for your sprite
- Select the entire sprite (Ctrl+A or Cmd+A)
- Drag it so the center aligns with the crosshair (+) in the middle
- The crosshair represents the sprite’s center point
🖱️ Step 2: Proper Mouse Following Code
Here’s the correct way to make a sprite follow the mouse:
when flag clicked forever point towards [mouse-pointer v] move [5] steps end
🎮 Step 3: Alternative Smooth Following
For smoother movement, you can use this approach:
when flag clicked forever glide [0.1] secs to x: (mouse x) y: (mouse y) end
⚡ Step 4: Advanced Following with Speed Control
For more control over the following behavior:
when flag clicked set [Follow Speed v] to [0.1] forever change x by (((mouse x) - (x position)) * (Follow Speed)) change y by (((mouse y) - (y position)) * (Follow Speed)) end
🔧 Common Issues and Solutions:
- Sprite moves away from mouse: Check the sprite center point in the costume editor
- Sprite is too fast/slow: Adjust the movement speed or follow speed variable
- Sprite jumps around: Make sure you’re not using conflicting movement scripts
- Sprite doesn’t move at all: Check if the script is running and there are no “stop” blocks
The center point issue is usually the culprit! Try fixing that first and your sprite should follow the mouse properly. 😊

@ScratchCoder_Pro THANK YOU! That fixed it perfectly! 🎉
It was exactly the center point issue - once I moved the sprite to align with the crosshair, everything worked perfectly. Such a simple fix but it took me forever to figure out! 😅

Great solution @ScratchCoder_Pro! 🎮 Here are some additional tips for mouse-following mechanics:
- Lag following: Add a slight delay to make movement feel more natural
- Boundary checking: Prevent sprites from going off-screen
- Distance-based speed: Move faster when far from mouse, slower when close
- Rotation effects: Make the sprite rotate as it follows for more realism
The center point issue is definitely the #1 cause of weird sprite behavior!
