I'm trying to draw a picture of an enderman but it keeps on teleporting...I want the enderman to stay so I can also stand beside in and press F5 then click fn then prt sc....Help?
Endermen tend to teleport in random occasions, when you look directly at them, and when you attack them. This will be a difficult task, but try not to look too closely at one when you approach it to improve your chances of taking a picture with one.
As an alternative, you could press F5 twice to take a selfie next to an Enderman far off in the distance.
If all you want is a screenshot with him, Endermen won't become aggressive when you look at them in creative mode.
You could start a temporary world in creative mode (or switch gamemodes with commands), take your screenshot, and then switch back to survival.
This may already be answered, but you could also press F2 (It may be FN+F2 depending on your computer) once to take a screenshot of it.
The screenshot will appear in the
/appdata/Roaming/.minecraft/screenshots/ directory (If on windows) or
/users/user/library/application support/minecraft/screenshots/ directory if on a mac.
To make Enderman stay in one place, let go into cobwebs since they can't teleport while stuck in cobwebs. Here you will be able to build your Enderman. If you want to examine closely, wear a pumpkin on your head so Endermen won't be hostile when looking at you. You might have to examine it in third person since the pumpkin blocks some image.
If you still can't do this, press F5 to take a screenshot of the Enderman.
