I made a script for an airstrike with a longsword, and a script for a pelican to come in and drop off it's riders near the red base in bloodgulch:

(script static void peli1

)

(peli1)
)

However, my problem is that even though I check not placed automatically for both of the vehicles, they still do not appear when they are supposed to in the script. Also, I manually created the vehicles with devmode in-game and tried to make them play the animations I made for them, but they just skip from frame 1 to 100 extremely fast. It looks like they just teleported away somewhere and came back after the animation is done.

Is there any way to fix my problems? (I'm pretty sure there is, as I have seen working animations such as b40_firefight for dropships and I also saw elefant's airstrike video with the longsword.)

Thanks in advance.
