I'll describe how to make a sprite grow in size smoothly as. the Grow value is too
If you start with a sprite size that's 100
When arrow is tapped
Grow by size multiplied by 1.1
This makes a sprite grow by 10 percent when tapped.
When you make a sprite in the distance grow bigger to look like it's getting closer, this code will help.
Just using the normal grow code and increasing by 1 makes the sprite grow too quick when small and grow too slow when large because only a number is being used and not a percentage like 1.1 which is 10 percent of the sprites current size.
