I'm diving into the world of three.js and have managed to create a basic particle app using it. However, I've noticed that the particles flow from the center, but I'd like them to move in a direction similar to what's shown in the screenshot attached (top right corner to bottom left corner). You can find the code I'm working on at . Any references or tips on achieving this particle flow would be greatly appreciated. Thank you.
It appears that your updateParticles function is currently only adjusting the z position of the particles:
particle.position.z += mouseY * 0.1;
if(particle.position.z>1000) particle.position.z-=2000;
To move the particles both vertically and horizontally, you will need to update the x and y positions as well.
particle.position.x -= mouseY * 0.1;
particle.position.y -= mouseY * 0.1;
if(particle.position.x<-500) particle.position.x+=1000;
if(particle.position.y<-500) particle.position.y+=1000;
Keep in mind that the size of your scene may require some adjustments to these values.
