I just found that Laser Letters script over at the eventscripts board and it's pretty awesome!

After porting it to sourcemod i've been trying to get the words/letters to rotate to keep them always facing in the same direction as the player, but i failed hard.

Basically the letters are a bunch of pointlasers drawn together. All points are directly on the x axis with different z coordinates. They are just offsets from the 0 0 0 middle.

E.g. the letter "A" would be

PHP Code:

new Float:fStart1[3] = {0.0, 0.0, 0.0};
new Float:fEnd1[3] = {10.0, 0.0, 30.0}; // left line
new Float:fStart2[3] = {20.0, 0.0, 0.0};
new Float:fEnd2[3] = {10.0, 0.0, 30.0}; // right line
new Float:fStart3[3] = {5.0, 0.0, 15.0};
new Float:fEnd3[3] = {15.0, 0.0, 15.0}; // horizontal connector 


Imagine spawning 3 BeamPoints at the eye position of a player + those offsets:

Now since we only modified the x axis, it's always parallel to the x axis, no matter where the player is watching at.

I tried to incorporate the eye angles, but i can't get it to rotate correctly.

PHP Code:

fInterestingAngle = fAngles[1] - 90.0;

new Float:fReverse;
if(fInterestingAngle >= 0.0)
    fReverse = 1.0;
else
    fReverse = -1.0;

fDistance = fStart[0] - fEnd[0];
if(fDistance < 0.0)
    fDistance *= -1.0;
fStart[0] = fReverse * (fStart[0] + Cosine(fInterestingAngle) * fDistance);
fStart[1] = fReverse * (Sine(fInterestingAngle) * fDistance);

fEnd[0] = fReverse * (fEnd[0] + Cosine(fInterestingAngle) * (fDistance));
fEnd[1] = fReverse * (Sine(fInterestingAngle) * (fDistance)); 


Attached is the script. Type "/ll hello" in chat to see the words in lasers above your head ;)

All credits belong to bonbon for her time to get those char offsets together!

I'd release it as an own plugin as is, but i first want to have the rotation working!

you need a rotation matrix, i'd read up on it first, if you're not very good at maths it will be difficult creating one.

u can use my matrix.inc file that i made for gravity gun plugin.

well..i cannot say it is perfect but..well...k.
