Resource:Custom coronas

This resource lets You create some coronas. Not just your typical gtasa coronas that often times fail to appear. Since in this case corona Elements are created using dxDrawMaterialLine3d MTA function. I have changed the behaviour of the material to act as cylindrical billboards do.

Overview

It is easy to use, gives a few options to manage coronas.

The resource itself adds exported clientside functions:

Exported functions

createCorona

Click to collapse [-]

Client

This function creates a shadered materialLine3d Corona.

bool exports.custom_coronas:createCorona(float posX,posY,posZ,size,int colorR,colorG,colorB,colorA)

Required Arguments

• float posX, posY, posZ: Position in world space.
• float size: Size of the corona.
• int colorR,colorG,colorB,colorA: Corona RGBA color emitted by the corona (0 - 255).

Returns

The function returns true if set successfully, false otherwise.

destroyCorona

Click to collapse [-]

Client

This function destroys a shadered materialLine3d Corona element.

bool exports.custom_coronas:destroyCorona(element coronaElement)

Required Arguments

• element coronaElement: A previously declaired corona element.

Returns

The function returns true if set successfully, false otherwise.

setCoronaPosition

Click to collapse [-]

Client

This function sets corona position.

bool exports.custom_coronas:setCoronaPosition(element coronaElement,float posX,posY,posZ)

Required Arguments

• element coronaElement: A previously declaired corona element.
• float posX, posY, posZ: Position in world space.

Returns

The function returns true if set successfully, false otherwise.

setCoroaColor

Click to collapse [-]

Client

This function sets light color values.

bool exports.custom_coronas:setCoroaColor(element coronaElement,float colorR,colorG,colorB,colorA)

Required Arguments

• element coronaElement: A previously declaired light element.
• float colorR,colorG,colorB,colorA: Corona RGBA color emitted by the corona (0 - 255).

Returns

The function returns true if set successfully, false otherwise.

setCoronasDistFade

Click to collapse [-]

Client

Set the Max distance of the corona to sync and the distance on which the it starts to fade out.

bool exports.custom_coronas:setCoronasDistFade(int MaxEffectFade,int MinEffectFade)

Required Arguments

• int MaxEffectFade: Set the Max distance of the corona to sync.(Must be greater than MinEffectFade).
• int MinEffectFade: Set the distance on which the corona starts to fade out.

Returns

The function returns true if set successfully, false otherwise.

Examples

local corTable = {}

function addStuff()

for i=1,30 do
	for j=1,30 do
	corTable[i] = createCorona(i * 7,j * 7,10,4,math.random()*255,math.random()*255,math.random()*255,1*255,false) 
	end	
end
end

bindKey("r","down",addStuff)

This creates a 400 coronas near position (0,0,0)

Of course when you want to use these functions in your resources you have to include the custom_coronas resource in meta.
