The latest version of Vox (v0.15) includes the particle editor. This can be accessed in-game by pressing the 'P' key.
The editor allows you control over all the different physical properties that modify a particle effect, such as gravity direction, starting velocity, colour, scale modifiers, etc.
All in-game particle effects are created using the editor, so you have direct control to the tools that are used to create the game's particle effects!
Once you have created a new particle effect, name it appropriately and then press 'Save'. Then insert it into your weapons in the weapon creation mode. (Press 'A' or select the 'Particle' checkbox)
Be sure to share any cool particle effects you create and post screenshots to your awesome creations.
This game is kinda like spore+minecraft which is just crazy :3
Now even me is able to work with particles! Thank you =)
No problem, glad you like the new feature :D
