I read a lot of threads about Path Spline Plugins but did you think about adding this kind of behaviour in CS2?
Also, I was thinking about another way to achieve it but I don't know if it could be possible.
The idea is to create a Texture that is a Mask that creates a path.
Could it be possible to have sprites following this shape?
Like that, the Sprites can have their own Bullet behaviour working individually but they follow smoothly the texture.If it is possible, it would be innovative :)
At present, I managed to get this behaviour by adding a lot of sprites and change Angle of Motion when the Sprite collides with the sprites used for the "path". This is really tedious but it works.
