help with instantiating gameobject at random postition from a target gameobject?

Hello all. I recently discovered that i cannot directly do a particle system with unity ui using screen space overlay, and i made some custom sparkle animations which will be done as an animated ui image using screen space overlay. what I am trying to do is to randomly instantiate that animated image at random positions around a ui image of a gem, that way it would replicate the effect of a sparkle which would otherwise be done with the particle system. How can I code this so that the spark prefabs get instantiated at random areas around the ui image (in screen space overlay) in contrast to being instantiated at

It sounds like the real question is “how to spawn objects at random locations within a UI.Image”?

Try this:

void spawnSparkles(GameObject sparkleSource, RectTransform image, int count) {
  for(int i=0;i<count;i++) {
    float x = Mathf.Lerp(image.rect.min.x, image.rect.max.x, Random.value);
    float y = Mathf.Lerp(image.rect.min.y, image.rect.max.y, Random.value);
    Instantiate(sparkleSource, new Vector3(x, y, 0), Quaternion.identity);

Let me know if it works! (or if I misunderstood what you’re asking)
