Edit: If anyone is reading this, please ignore the huge blueprint below, and check out the nicer one I made near the bottom of the page.
Notice how in your blueprint for shrinking, you’re setting the value to the current value - 1? If the current value is 1 it ends up 0. When the scale is 0 it is nothing, and this causes the camera to fall to the ground and half way through it.
Now, as for the smooth transition between sizes you requested, you need to use a tick event that keeps adjusting the size by tiny increments until it reaches it’s target size.
I’ll show you a blueprint I made, but first let me explain exactly what it does: It allows you to use 2 buttons to switch between just 3 precise sizes: small, medium, and large. The transition between sizes is not instant, you can see a smooth grow/shrink.
(Note: The “get max element” node I’m using returns the highest float in the vector. But in this case, the values of x, y, and z are all the same. The only reason I do this is because you cannot compare two vectors to see which is greater. I needed to use a float. If you plan on making the values of x, y, and z be different, you will have to find another way to check the values. Let me know if you need any help with that.)
For this blueprint, I created 3 variables. The one called “normal size” has a default value of true. (For the inputs, I’m using d-pad directions, but you can use A and E of course.) (Sorry the nodes are so compacted, I wanted to fit them all in frame. Just pay close attention to where the wires are going. ^^;
