[SNIPPET] Convert 3D position to 2d Radar screen pos

Function:

0AB1: @POSITION_TO_RADAR 7 XYZ 0.0 0.0 0.0 RADAR_POS 400 400 DISTANCE_MULTIPLIER 1.5 MAX_DISTANCE 300.0 _STORE_TO 1@ 2@

This function converts 3D position to 2D Radar position like on the Minimap.

You can make things like this:

I edited the code a bit, it was giving elliptical results instead of circular because there was no adjusment for x/y ratio 640/480

Edit: btw it's better to use 0509: 13@ = distance_between_XY 0@ 1@ and_XY 10@ 11@ instead (otherwise radar position if something is above/under you)

Re: Convert 3D position to 2d Radar screen pos

Is it possible to check the radar autozoom ? (the map zom/unzoom at different car's speed), so that the point stay at the good position on the minimap independent of the speed ?

Re: Convert 3D position to 2d Radar screen pos

If you wanna make it for the RADAR, get the center of your radar pos, then adjust the DISTANCE MUTLTIPLIER without moving.
Then adjust the velocity compensation (zoom/unzoom map) with this code


CODE BY MONDAY
Code: 
06AC: 21@ = actor $PLAYER_ACTOR movement_speed
    if 0021:   21@ > 50.0
    then
    21@ = 50.0
    end
006B: 21@ *= 21@ 
17@ = -0.514 //by adjusting this you change how big is compensation of the position due to speed
0017: 17@ /= 2500.0
006B: 17@ *= 21@ 
000B: 17@ += 1.0 // DISTANCE MUTLTIPLIER without moving

//17@ = distance multiplier

if i have fixed coordinates and I am too far "assuming MAX_DISTANCE 300.0 meter" will it try to display on radar even i am out of reach or not? regardless, tyvm
