Holoemitter shape challenge!

[dpidcoe]

Here's mine, it draws a sphere that follows a player.

edit: I should probably also add, this isn't really that serious of a submission

[Magos Mechanicus]

I can't seem to get any kind of continuous shape following a moving player either, only keep redrawing it until he stands still to watch the lights. But I'll keep plugging away at it - see if I can't at least get it to rotate with the player and such.

Edit: Can we also submit in the form of an Expression 2 code? Neither save nor dupe seems to be working with this one.

[Takinu]

Expression gate 2? Yeah, I did say ANY two chips.

I hate these two rules. If you get rid of them, check this out.

Also, I made a superellipse drawer, but I'm not sure if I have a dupe of it.

I also graphed z=sinc(x*x + y*y). I think I may have a dupe of that.

[Magos Mechanicus]

I know I saw you dupe it once, at least. Now that you're in I guess I don't have too much of a chance but anyways, here goes.

@name Holochallenge
@inputs Go Reset Player:entity Speed Mode A B C D E F
@outputs Relpos:vector Abspos:vector X Y Z AbsX AbsY AbsZ
@persist Starttime

if(Reset&~Reset){Starttime=curtime()}
if(Go){
    if(!Mode){A=17.5,Speed=180}
    if(Mode){D=round(D),E=(!round(E) ? 1 : round(E)),F=(!round(F) ? 1 : round(F))}
    interval(80)
    Passedtime=curtime()-Starttime
    if(!Mode){X=A*(1+cos(Passedtime*Speed)),Y=A*sin(Passedtime*Speed),Z=2*A*sin(Passedtime*Speed/2)}
    if(Mode){X=A*sin(Passedtime*D*Speed),Y=B*sin(Passedtime*E*Speed),Z=C*sin(Passedtime*F*Speed)}
    Relpos=vec(X,Y,Z)
    Abspos=Player:pos()+(36+Z)*Player:up()+(5+X)*Player:forward()+Y*Player:right()
    AbsX=Abspos:x(),AbsY=Abspos:y(),AbsZ=Abspos:z()
}

The default mode (Mode input = 0) will make the curve shown earlier - a Viviani's curve centered in front of the player. It will appropriately rotate - if you center it on an NPC it will even appropriately pitch and roll with him, something players normally can't do. The secondary mode (Mode !=0) was more experimental, because chinoto's idea of lissajous curves sounded interesting. It's a curve generator, and will generate lissajous curves in space based on inputs A-F. D/E and D/F must be rational numbers or else the curve won't be closed and there will be no repeating pattern - these inputs are therefore sanitized a bit, unfortunately eliminating also some closed curves.

Wiring is pretty straightforward. Make a Target Finder, let it target players. Wire the expression's Player input to the Target Finder's 1_Ent output. The rest go to buttons (Go/Reset/Mode) or freely fiddlable constant values (Speed/A-F, I recommend a Speed of around 10 for the curve generator.). Use an emitter with Grid and UseGPS=1, and wire the emitter's coordinate inputs to AbsX/AbsY/AbsZ as appropriate (the X/Y/Z give relative positions and can be used to preview the generated curve in a static position and rotation, for instance). Using the vectors still seems to give mainly errors.

Nah, I'm not that great.

Sweet. I'll make a lissajous generator and also one for hypotrochoids.

And then I win.

EDIT:


Attached is the Expression2 code.

[chinoto]

I actually made a hypotrochoid/spirograph or maybe it was epitrochoid, whatever small change in arithemtic, it looked pretty cool but the better designs took awhile to draw.

[Magos Mechanicus]

You shouldn't make so many pentagrams.
The power of Zombie Jesus compels you!

[Mr Affinity]

It would be easy just make the cool figure, then add it to the players x y z position.

[chinoto]

Players move a lot, so you can't have something to complicated or else it wont ever be seen, thats why my idea was to make a spiral that follow the player.
