About this Mod
Ever wondered where your arrow, snowball, or potion will land? This mod gives you a visual preview of projectile trajectories and highlights the target impact zone—perfect for planning shots with precision.
🔎 Features
- Trajectory Visualization: See the path your projectile will follow before you launch it.
- Target Highlighting: Know exactly where your shot is likely to land.
- Customizable: Tailor the look of the trajectory line, target outline, and target highlight to suit your style.
- Accurate: Unlike most other mods that do this, PTP uses accurate maths, offsets and physic. It has correct throwing directions offsets, physic steps order, initial velocity, air drag and gravity for every projectile it supports!
⚙️ Configuration
To edit the settings of the mod:
- Use Mod Menu
- Use the command
/ptpConfigto open the config screen - Edit the config file in
.minecraft/config/ptp.json
⚠️ Limitations and notes
- Minecraft projectiles often have a random offset, so the actual impact may sometime differs a bit from the preview.
- Modded items are not yet supported. If you want compatibility with a specific mod, open an issue on Github and suggest it, I'll do my best to add it.
🛑 Usage on servers
This mod doesn't work on servers to prevent using it as a cheat in PVP. If you want to have it on your custom servers, you still can, just install the mod on both, the client and the server.
