You can set the Argument of the Programmable Block to a specific command string to dynamically change missile behavior during launch. The command string is in the following format:

<PARAM1>:<VALUE1>,<PARAM2>:<VALUE2>,..... and so on.

Example:

R_REM:REMOTE_1,V_DVR:1.2,V_DRIFT:FALSE

The available parameters are as below:

MODE - Select the Missile Launch Mode. [Integer]
R_REM - Select which Remote Control on launching ship to use for initial lock-on pointing. [String]
R_TAR - Select which Text Panel on launching ship to use for initial lock-on GPS coordinates. [String]
R_CAM - Select which Camera or Turret on launching ship to use for Camera Guidance. [String]
V_DVR - Set higher value for less drift, and lower value for more drift. DO NOT set 1 or below. [Double]
V_LS - Set launch duration in seconds, where missile flies forward without turning. [Double]
V_DRIFT - Whether Drift should be used. [TRUE/FALSE]
V_LEAD - Whether missile should Lead Target. [TRUE/FALSE]
V_DAMP - Whether Natural Gravity Dampening should be used. [TRUE/FALSE]
P_VT - Whether to use Vertical Takeoff during launch. [TRUE/FALSE]
P_EMR - Whether to use negative GFD beam width to exclude missile's radius, rendering grids with same size as the missile invisible. [TRUE/FALSE]
P_WFT - Whether to fly straight first until LOCK command is given via R_TARGET Text Panel to start homing. Activating this will ignore launchSeconds variable. [TRUE/FALSE]
P_EMC - Whether to allow missile to read Private Title of the R_TARGET to get command during missile homing. Refer to In-Flight Missile Commands Section for more information. [TRUE/FALSE]
