MLPV2 Ball Script with more flexible parameters

• MLPV2
• Back to MLPV2_Addons

<lsl>// ~capture Script V1.01 // drop into a ball // //MLPV2.4z9 //Chaz edit 2012 to give control over (1) how visible adjusting beams are, (2) how high up balls rez, and (3) and over floating text on balls //that's the only change, to make these parameters easily accessible and put them all in one section near top of script

// MLPV2 Version 2 by Learjeff Innis. Based on // MLP MULTI-LOVE-POSE V1.2 - Copyright (c) 2006, by Miffy Fluffy (BSD License)

// To make ball phantom, put "*" as the first character in the ball's description // or just make the ball phantom (which really works better for HUDs). // The rest of the description, if any, is used for the sit pie menu and floating text. // To make this take effect, use STOP to unrez the balls, and then select any pose.

// v2.4j - cancel old listen on rez // v2.4m - handle control keys! To enable, begin ~ball description with a plus sign ("+"), following "*" if any. // v2.4p - page up & down to enable/disable adjustment // v2.4x - moved SitTarget to top.

//chaz adjustable parameters start float AdjustBeamTransparency = 0.4; //0.1 is practically invisible; 1.0 is solid (0.0 <= alpha <= 1.0) string BallFloatingText = "";//any floating text to display above the balls vector SitTarget = <0.,0.,-.5>; // Change this to <0.,0.,-.15> or lower, to raise balls above cushion //chaz adjustable parameters end
