Adv-Hologram Application

[Zeroedge9]

This tutorial builds upon my previous tutorial on basic holograms, it's also oriented towards applying them to some common use and including some examples.

Alright, Lets begin.

@name Zero's Holo Hud
runOnTick(1)
E=entity()
O=owner()

if(first())
{
    Radius=300
    holoCreate(20)
    holoModel(20,"hqcylinder")
    holoScale(20,vec(0.25,0.25,1))
    holoCreate(21)
    holoModel(21,"hqcylinder")
    holoScale(21,vec(0.25,0.25,0.5))
    holoCreate(22)
    holoModel(22,"hqcylinder")
    holoScale(22,vec(0.25,0.25,0.5))
    holoCreate(23)
    holoModel(23,"hqcylinder")
    holoScale(23,vec(0.05,0.05,0.1))
    holoCreate(24)
    holoModel(24,"hqcylinder")
    holoScale(24,vec(0.05,0.05,0.1))
    holoCreate(25)
    holoModel(25,"hqtorus")
    holoScale(25,vec(0.1,0.1,0.1))
}
#Defines if Grav Gun can grab
if(O:aimEntity()&O:aimEntity():mass()<250&!O:aimEntity():isFrozen())
{
    C1=vec(155,0,0)
    if(O:aimEntity():isPlayer()|O:aimEntity():isNPC())
    {
        CX=vec(155,0,0)
        C1=vec(0,155,0)
    }        
}
else{C1=vec(0,155,0)}
#Health meter logic
T=O:shootPos()+O:eye()*8
Hp=O:health()*2.55
HpE=O:aimEntity():health()*2.55
C2=vec(255-HpE,HpE,0)
C3=vec(255-Hp,Hp,0)

#Grav gun bar
holoPos(20,T+O:up()*3)
holoAng(20,angnorm(O:eye():toAngle())+ang(0,0,90))
holoColor(20,C1,160)

#Owner HP
holoPos(21,T+O:right()*5)
holoAng(21,angnorm(O:eye():toAngle()))
holoColor(21,C3,240)

#Enemy HP
holoPos(22,T+O:right()*-5)
holoAng(22,angnorm(O:eye():toAngle()))
holoColor(22,C2,HpE)

#Crosshair 1
holoPos(23,T)
holoAng(23,angnorm(O:eye():toAngle())+ang(0,0,90))
holoColor(23,vec(0,0,255),200)

#Crosshair 2
holoPos(24,T)
holoAng(24,angnorm(O:eye():toAngle()))
holoColor(24,vec(0,0,255),200)

#Locked on Ring
holoPos(25,T)
holoAng(25,angnorm(O:eye():toAngle())+ang(90,0,0))
holoColor(25,CX,HpE)

#Comment all this if in public server. The E2 will shutdown from ops overload otherwise
#This section will place a holo around props within a certain radius of it.
findByClass("prop_physics")
findExcludeEntity(O)
R=findToArray()
for(I=1,R:count()) 
{
    if(O:pos():distance(R[I,entity]:pos())<Radius)
    {
        holoCreate(I)
        holoParent(I,R[I,entity])
    }
    else{holoDelete(I)}
    holoPos(I,R[I,entity]:pos())
    holoScaleUnits(I,R[I,entity]:boxSize())
    holoAng(I,R[I,entity]:angles())
    holoColor(I,vec(0,0,155),190)
}

There's a reason my holos start off at 20+. The loops creates all the holos below 20.

I'm going to go over all the technical parts of this holo and im going to assume my old tutorial was read.

#Defines if Grav Gun can grab
if(O:aimEntity()&O:aimEntity():mass()<250&!O:aimEntity():isFrozen())
{
    C1=vec(155,0,0)
    if(O:aimEntity():isPlayer()|O:aimEntity():isNPC())
    {
        CX=vec(155,0,0)
        C1=vec(0,155,0)
    }        
}
else{C1=vec(0,155,0)}

This code basically says. If i look at a prop that the grav gun can grab(not 250g+ or frozen), turn the indicator holo red. If i look at a Person or an NPC make the target ring red and leave the indicator holo green.

#Health meter logic
T=O:shootPos()+O:eye()*8
Hp=O:health()*2.55
HpE=O:aimEntity():health()*2.55
C2=vec(255-HpE,HpE,0)
C3=vec(255-Hp,Hp,0)

This portion of the code will show the owner's Hp through a color coded bar as well as any players/npc's you look at.

holoAng(index,angnorm(O:eye():toAngle()))

This line is very important. it is how the hologram keeps its angle oriented in the same direction when you look aroound.

#Comment all this if in public server. The E2 will shutdown from ops overload otherwise
#This section will place a holo around props within a certain radius of it.
findByClass("prop_physics")
findExcludeEntity(O)
R=findToArray()
for(I=1,R:count()) 
{
    I=clamp(I,0,19)
    if(O:pos():distance(R[I,entity]:pos())<Radius)
    {
        holoCreate(I)
        holoParent(I,R[I,entity])
    }
    else{holoDelete(I)}
    holoPos(I,R[I,entity]:pos())
    holoScaleUnits(I,R[I,entity]:boxSize())
    holoAng(I,R[I,entity]:angles())
    holoColor(I,vec(0,0,155),190)
}

This is an unoptimized for loop i made for the fun of it. The concept of this is to create holograms around the props nearby and just have some fun with it. Since i didnt have the time to fully optimize the code 100% the chip will shutdown if too many props are spawned. to solve the shutdown comment everything below the warning i gave.

If anyone needs clarifications let me know and i will try and help. Also throw out some requests and i will try to see if i can help with it.

if you liked it too =D

[Unsmart]

Have you even checked if your code works? you dint persist radius, so I assume it will fail. I don't get what your trying to do/make/explain i this tut.

[Zeroedge9]

Yea it works. i test it by placing props in a line and standing at the end of that line. only the ones in range were selected (though it'd be nice if findInSphere() worked)

[smellslike]

pretty nice tutorial, really builds from your last one. Needed a few more explanations though, i wouldn't have understood if i didnt know this already.

[Zeroedge9]

Can you give me examples on what i should clarify?
