How do I create river creating splash

Hey again, I need help on making a ' water splash ' spawn when object interacted with river. I made the splashing animation but I'm not sure how to make it spawn on the position where the object interact. Can someone help me with this? thanks.

Let me know if you need the capx

First of all: please always provide the capx if it isn't too big or too messy.

The easiest way is to add an event for the object that interacts with the river:

[object]: -> On collision with [River][/code:i16x9zrx]

That event would contain an action to create an object at the current position of the collided object.
(You may need to add an imagepoint to make the creation location more accurate)
