Help Neareast part from vehicle

ZaaxHash · Nov 23, 2024

Is possible get nearest part vehicle from my aim, or get some point collision closer?

Zin · Nov 24, 2024

Assuming you mean to get the closest point of "Vehicle collision" which maybe easily done with this [SNIPPET] Get aiming positionaim ???? although depends on how opcode 06BD works, if not might be able to find something in game memory.

ZaaxHash · Nov 24, 2024

I expected get parts of vehicle as hood, trunk, side of car, roof, bump, to check which one my aim is more closest, or other thing like a, get vehicle collision point nearest a screen coords
I hope it's clearer now

So do you want the XYZ coordinates of the vehicle collison? Or do you want a script that will give you "Car: X Component: X" of what you are aiming at?

Start by finding the car that is closest to your crosshair and save it for reference. This can be done by checking the distance between the crosshair and all nearby cars. Once you have the nearest car, go through all its parts one by one. For each part, calculate how far it is from the crosshair. Compare the distances, and keep track of the part that is the closest to the crosshair. This way, you can identify the specific car part nearest to your crosshair.

Yes, I want to get XYZ of collision, I was trying to get the vehicle parts and check the player fov as @Opcode.eXe said finally, but it didn't work out as expected, some vehicles seem to be missing some components.

But I saw an opcode that might help:

Code:

0BFF: process_line_of_sight start 0@ 1@ 2@ end 3@ 4@ 5@ check_solid true car true actor false object true particle false see_through_stuff false ignore_some_objects_for_camera true store_col_point_to 6@ entity_to 7@

So if a player (in this case the first 3 parameters) is aiming at another player (the next 3 parameters) and in the middle there is a vehicle, is it possible with this or another opcode to determine the coordinates or distance to this vehicle?

Yeah those codes put out by Opcodexe are for general parts defined in a vehicles dff I believe. That opcode you put should work also providing it works the same way 06BD detects obstacles. Here's a script for testing what you want.

Code:

// This file was decompiled using SASCM.ini published by GTAG (http://gtag.gtagaming.com/opcode-database) on 14.6.2013
{$CLEO .cs}

        not model.Available(3000)

        model.Load(3000)
    ELSE

        08D2: object 0@ scale_model 1.0
        0382: set_object 0@ collision_detection 0
        BREAK   
    END
END

WHILE TRUE
    WAIT 0
    
    IF
        KEY_DOWN 2
    THEN
        CALL @GET_AIMING_POS 0 1@ 2@ 3@ 4@
        object.PutAt(0@, 1@, 2@, 3@)
        0AD1: "%d %f %f %f" 1 4@ 1@ 2@ 3@
    END
    
END

    Actor.StorePos($PLAYER_ACTOR, 1@, 2@, 3@)
    0A9F: 5@ = current_thread_pointer
    5@ += 80
    0A8E: 6@ = 5@ + 12 // int
    0AA6: call_method 5327216 11989032 num_params 6 pop 0 6@ 5@ 3@ 2@ 1@ 4@

    THEN
        31@ = TRUE // CAR DETECTED
        BREAK
    END
END
0@ = 0.0
1@ = 0.0
2@ = 0.0
005B: 0@ += 8@ // (float)
005B: 1@ += 9@ // (float)
005B: 2@ += 10@ // (float)
4@ = 0.0 // RESET THE AIM RADIUS 
0AB2: 4 0@ 1@ 2@ 31@

It's not that accurate however by the sounds of it I don't think it's possible to accurately determine where another player is aiming (atleast not to the same accuracy you can read your own aim). You should be able to replicate this for other players aim with this long lost snippet. Basically you would just loop through distances at set intervals (like in the get_aim_pos code) until it detects car collision (or nothing).

Code:

:get3DXYZInFrontOf{X,Y,Z,ZA,YA,Distance}
{   
   Return:
       PosX-InFrontOf
       PosY-InFrontOf
       PosZ-InFrontOf
      
   Example: 0AB1: call_scm_func @get3DXYZInFrontOf 6 XYZ 1@ 2@ 3@ Z_Angle 4@ Y_Angle 5@  Distance 7.0 Return_XYZ_To 6@ 7@ 8@

}
3@ *= -1.0
02F6: 6@ = sine 3@
006B: 6@ *= 5@
005B: 0@ += 6@
02F7: 6@ = cosine 3@
006B: 6@ *= 5@
005B: 1@ += 6@
02F7: 6@ = cosine 4@
0073: 5@ /= 6@
02F6: 6@ = sine 4@
006B: 5@ *= 6@
005B: 2@ += 5@
0AB2: ret 3 0@ 1@ 2@
