Lights in GTA 2 Coding

You usually set up lights in the map editor, but you can also add them during a mission. For example, player goes to rob a bank and sound and flashing lights appears. 

LIGHT uniquename

Like sound, this reserves a spot for a light later on. To activate it, add this code: 

uniquename = CREATE_LIGHT ( X , Y , Z ) radius intensity ( red , green , blue ) ondelay offdelay random

Seems strange doesn’t it? This is what the parameters mean:

Range Description
Radius 0 to 8 Radius of the light effect in cubes.
Intensity 0 to 255 Brightness of the light.
red 0 to 255 How much of each colour to add in normal RGB notation.
green
blue
Ondelay 0 to 255 Time a flashing light shines for. 20 is a fairly decent speed.
offdelay 0 to 255 Time a flashing light stays dark for.
Random 0 to 255 sets the maximum number of frames to randomise the delay timings by.

Let me show you an example: 

light01 = CREATE_LIGHT ( 12.5 , 56.5 , 3.0 ) 8 255 ( 255 , 255 , 255 ) 0 0 0

If you want to create a light straight off, add this code: 

LIGHT uniquename ( X , Y , Z ) radius intensity ( red , green , blue ) ondelay offdelay random

Again, I'll show an example: 

LIGHT light02 = ( 67.5 , 78.5 , 2.0 ) 8 255 ( 255 , 0 , 0 ) 0 0 0

That code would create a red light at those coordinates.

Editing Lights

As well as creating lights, you can also edit them too with these 3 commands: 

CHANGE_INTENSITY ( lightname , newintensity )
CHANGE_COLOUR ( lightname , newred , newgreen , newblue )
CHANGE_RADIUS ( lightname , newradius )

Again, they are all simple to use. The lightname is a light you created by the way. Your codes could look like this: 

CHANGE_INTENSITY ( light03 , 150 )
CHANGE_COLOUR ( light04 , 255 , 0 , 255 )
CHANGE_RADIUS ( light05 , 8 )
