[script] - Moving target

[punkatux 10]

Hello!

I post here the script I made which is useful and easy to use when you want to make some kind of target to move smoothly between 2 defined positions. Feel free to post any bug-report here. If you use the script, please keep the header unmodified. The header is also filled with informations how to use the script, so check there.

While I saw some similair scripts around, this one is written in performance-friendly way and should be independent of server FPS.

move_object.sqf

/*

version: 0.1

This script moves object smoothly between two markers with either constant or varying speed.

Parameters: [object, marker_start, marker_end, fps, speed_min, speed_max]
	object 		- object that will move between markers
	marker_start 	- marker placed at initial position
	marker_end	- marker placed at target position
	fps		- wanted FPS, must be > 0
	speed_min	- minimun speed of object in m/s
	speed_max	- maximum speed of object in m/s
			- speed_max is optional parameter, in case it's missing, target moves with constant speed of speed_min

For constant speed, use this - 2 m/s:
	[this, "marker_start", "marker_end", 100, 2] execVM "move_object.sqf";

For speed in some range, use this - 2~5 m/s:
	[this, "marker_start", "marker_end", 100, 2, 5] execVM "move_object.sqf";

Damn, put that in configs & scripting section, instead of mission-making & scripting. Can I fix it somehow, or can any admin do so?

The script work fine in local editor, but in a server the target popup move to jump, to jerky. any solution?

sorry for my english, i'm italian

Thx
