Time to start
Take your life cycle (Don’t change then settings.) and 2 wire repeaters. Make a loop by taking both wire repeaters and wire them together like this.
Now take the life cycle and wire it to one of the wire repeaters.
Wire the life cycle to the camera point like this.
Then wire the life cycle to the speed modifier like this.
The speed modifier speed should be set to 0.
Now take 4 of the counters and set to the following setting.
Now set the target value for each counter based on the number bellow it.
For the counter with target value 10 you can change it to how long you want the loading screen to last.
Place the barrier make it black and the alpha should be 1. Take 1 of the text and make it say Loading the font and the size are personalized to what ever you want. Put the camera point in the middle of the barrier, it should look like the following.
Now take 3 text and insert a period. the 3 text should look like this.
Also make them not visible to game starts and hide on the following channel… reset.
Now wire counters 1,2, and 3 to 1 text like this.
Now for the counter with target value 4 the settings should be like this.
All the counters should reset on channel reset, only the one with target value 10 should not reset
Move text in place in order from counter 1,2, and 3 to the black barrier, it should look like this.
(I know my periods are not aligned perfectly
)
Now for the counter with target value 10 wire it the to camera point like this.
Take the last speed modifier (Don’t change the settings) and wire it the same counter like this.
Note: The loading screen will not work if a player joins late.

Reason behind this guide.
Other than that I could not find any guides on this, a loading screen can make you map a little more creative and unique! Hope this guide helps!
Also don’t say great guide, there’s a 
button for a reason!
