Works for me in v118 (see attached video)
Did you read the included ReadMe file????
Here it is...
; FPS Creator - Artificial Intelligence Script
; Created by Conjured Entertainment on September 6, 2010
; Created for the Cosmic Prophet for his Jetpack
Notes:
I did not have much time to work on this script, so my testing was limited and I’ll have to come back another time to improve on this script. Unfortunately, I could not get the shaders to work properly because they refuse to alpha fade, which is necessary for transparency on the pickup. If you can get a shader to work with a script edit, then please let me know.
Directions:
Place the jetpack model in your map, so the player can pick it up. (To start the player with it then simply place a jetpack on the player’s start marker)
After picking up the jetpack the player will see the jetpack’s icon just under their weapon via a HUD. This HUD will indicate the amount of fuel left as well as indicating when the thrusters are being fired and fuel is being used.
Pressing the LEFT SHIFT KEY will fire the thrusters, thus causing the player to lift. This does not interfere with the sprint function of the left shift key, because the sprint is applied after the ‘W’ key is already pressed. So, if you press ‘W’ to move forward and then hold the left shift key, you will sprint as you normally would and without the thrusters being fired. However, pressing the left shift key first will cause your thrusters to fire on the jetpack, then pressing the ‘W’ while holding the left shift key would cause forward motion in flight.
The directional keys of ‘W’, ‘A’, ‘D’, and ‘S’ will cause the player to descend while thrusting. This is the proper way of descending while flying with the jetpack, and not by freefalling. Freefalling will result in a return to the jetpack’s position prior to the freefall on the very next thrust. Once you have landed safely and want to run, then you should let off of all the keys momentarily in order to stop the thrusters. If the thrusters are being fired, then you are using fuel, whether you are flying or running. So, be careful not to run around with your thrusters still on once you have landed.
WARNING:
Freefalling, or descending too fast, can cause injury to the player! Descending should be done with the directional keys (W, A, S, D) while you are thrusting. However, this should be done in moderation and not all at once. Descending too fast can result in an unwanted freefall and cause injury to the player. You will hear the thruster’s sound begin to fade if you are falling too fast.
Free falling is a known issue, and that is why you need to use the directional keys to descend.
Feel free to modify the script.
I am not sure why it is not disappearing though, if you are not using a shader on it. (which beta are you using? I am using beta 9)
