How to Make Flashing Text
First, get the text object that you want to flash. Add a new rule, whenever you want it to flash, and get a repeat forever block. Put two normal repeat blocks in the repeat forever block. Each repeat block should be 20.
Repeat 20 Times
Inside each Repeat 20 block, put a Set Invisibility block. In the first one, put +. In the second, put -.
First One :
Repeat 20 Times ; Set Invisibility _ + _
Second One :
Repeat 20 Times ; Set Invisibility _ - _
Now, in the first bubble of each, get the "Invisibility as a %" value. (Must be the value of the flashing text).
In the second bubble, put 5 for each. Now press play, and your text should be flashing! Any Questions? Reply with @Nerd4Ever to notify me.
