Inspiration:

The idea was to create a destruction effect when an object is hit by another object (sphere). At the same time, I also want to change the color of the sphere when it hit the other object.

Blue Print Walkthrough:

For the destruction of the wall, I used the fraction mode without using buleprint. However, for the changing colour of the sphere, I tried to create script for both constructive script and event graph. I also tried to edit the timeline editor, so the colour can change according to the time.

Success:

I learned how to change the colour of the sphere without changing it manually.

I also learned how to destruct the wall when interacting with the character.

Challenge

I haven’t figure out how to use the sphere to destruct the wall and keep the colour changing. Cuz when I tried to use the sphere hit the wall, the colour just turned back to black, so I can only leave the sphere above the wall.
