Number of parameters: 2
Parameter #	Type	Description
1.	integer	blip_handle
2.	integer	blip_display
Return value:
Type		Description
None

Changes how a blip is displayed in both the radar/map and the world.

Know values for blip_display

Value	Is it drawn on the radar/map?	Is it drawn on the world?
0	NO	NO
1	NO	NO
2	YES	YES
3	NO	NO
4	YES	YES
5	YES	NO

These values were infered doing in-game tests. Pay attention to the numbers shown in the radar next to the contact_blips (colored in dark yellow). On the first image these numbers represent the index of each blip in blip_array[] and their blip_display value. On the second image those numbers represent only their index in blip_array[] while their blip_display value is always equal to 4. Note how the blips are displayed on the second image relative to the first one.

The blips were created in a for loop that also changed their blip_display value:

/*
While you may see 7 blips here this code is responsible for creating
only the "contact blips" (the ones in the background)
*/

//The display values were defined in an enum.
//They vary from 0 to 5 with BLIP_DISPLAY_0 being 0 and BLIP_DISPLAY_5 being 5

Blip blip_array[6];
eBlipDisplay display_array[] = {BLIP_DISPLAY_0, BLIP_DISPLAY_1, BLIP_DISPLAY_2, BLIP_DISPLAY_3, BLIP_DISPLAY_4, BLIP_DISPLAY_5};

for(int i = 0; i < 6; i++)
{
	f32 offset = -8.0 * float(i);
	//For some reason "contact blips" and "coord blips" (light yellow, on the foreground) are gigantic
	AddBlipForContact(952.727, -508.730 + offset, 20.0, &blip_array[i]);
	ChangeBlipDisplay(blip_array[i], display_array[i]);
