Hi All,

I can move a shape/SF Symbol along a path using Animatable Data to step long the path. That works well.

Is there a good way of leaving a tacer/trail behind the movement of the shape/symbol? I have worked out a way of doing it (drawing a trail of images along the path as the object moves), but it feels quite ineffcient.

Any ideas appreciated.

Thanks for the video link. Sarcasm is the lowest form of wit.

I'm not seeking a code review to make my code more efficient. I'm asking about techniques. Is there is a built in technique within SwiftUI to create tracers/trails on moving objects. Like 'Trail Renderer' on Unity for example? If not, what other techniques would be the most likely candidates to be adapted for that purpose?

You could look at SKEmitterNode, or the older CAEmitterLayer, for your techniques. Search for these terms in HWS, or elsewhere.

You can specify the lifetime of a particle, which usually is a sprite, therefore an image.
