Strategic Remote Gun Placement

Name: LUA Scripted Strategic Remote Gun Placement
Type: Scripted Weapon
Script Version: 1.1
GM Version: 9.0.1

Short Description: Strategic Remote Gun Placements, or SRGPs, are capable of firing an explosive projectile over a long distance.

Long Description: SRGPs use a sophisticated laser-tracking technology to determine the target of a projectile. Using simple trajectory calculations, the SRGP adjusts the elevation and rotation angle using a rotating base according to the distance and location of the target. Two optional firing modes include height and velocity adjustments. A manual firing mode version is available.

-- Installation Instructions --
 * Place weapon_srgp.lua in the gmod9\lua\weapons\ folder.
 * Adjust any variables in the "User Variables" section of the weapon_srgp.lua file if needed.
 * Start a single or multi player game.
 * To give yourself the weapon, open the command console and type:
     lua _PlayerGiveSWEP(1, "weapons\\weapon_srgp.lua")

-- Usage Instructions --
 * Switch to the weapon.
 * There are three firing modes. To switch between them, use the reload button (default "r"):
    1. Placement mode
        - Primary fire: Click/hold to place SRGP.
        - Secondary fire: Click to delete all SRGPs.
    2. Firing mode
        - Primary fire: Click/hold to fire all SRGPs.
	- Secondary fire: Hold to aim all SRGPs at designated point.
    3. Adjustment mode for regular version
        - Primary fire: Hold and look up/down to adjust current adjustment mode.
        - Secondary fire: Click to toggle adjustment mode.
    3. Adjustment mode for "Manual Adjustment" version
        - Primary fire: Hold and look up/down to adjust velocity.
        - Secondary fire: Hold and look up/down to adjust fire angle.

 * Adjustment modes:
    1. "H" - Height:
        - This mode is for adjusting the height of the trajectory.
        - The setting for this mode ranges from 0 to 100 percent. The percentage is the percent of the current level's ceiling height. For example: If the current level has a ceiling at 500 feet, a 50 percent height adjustment will shoot at 250 feet.
        - This mode is particularly useful for levels with low ceilings. Set the height adjustment even to 100 to have the projectile skim the level's (possibly low) ceiling.
        - Note that this mode may take away from the max range of the SRGPs. Use velocity adjustment for maximum range.
        
    2. "V" - Velocity:
        - This mode is for adjusting the starting velocity of the projectile.
        - The setting for this mode ranges from 0 to 2000 units per second. The faster the velocity is set, the longer the range will be.
        - This mode is useful for reaching the max range of the weapon.
        - A high velocity also means that the projectile may hit the ceiling (watch for a RED WARNING SIGN labeled "TOO HIGH!" if the HUD is enabled). Use the height adjustment mode if this becomes a problem.

 * The Heads-Up Display (HUD) displays information for the first SRGP you placed.
     - This HUD displays many calculations, such as launch angle, velocity, height, distance, and time. It also includes range and ceiling indicators.
     - Note that the HUD has an inherently slow update rate due to calculation complexity. Efforts are being made to fix this problem.
