I'm trying to draw a marker for the player to walk into using this class:

 

Spoiler

class DrawMarker : Script
    {

        public static void drawMarker(Rage.Vector3 target, System.Drawing.Color color)
        {
            GTA.Math.Vector3 Target = new GTA.Math.Vector3(target.X, target.Y, target.Z);
            GTA.World.DrawMarker(MarkerType.VerticalCylinder, Target, GTA.Math.Vector3.Zero, GTA.Math.Vector3.Zero, new GTA.Math.Vector3(1f, 1f, 1f), color);
            return;
        }

    }

I'm using this code to call it from another class (a callout): 

Spoiler

DrawMarker.drawMarker(target, System.Drawing.Color.Yellow);

And in the log it is throwing this error message : "Object reference not set to an instance of an object"

Can anyone help with this? I've been trying for ages to get this working so I can update my mod but nothing seems to work.

 

Thanks in advance 🙂

It seems to be you are mixing code between RAGE Plugin Hook and ScriptHookDotNetV, I am not sure how well this works. I could imagine there being quite a few problems when calling a native via SHDN while being in RPH's script thread - V's scripting engine is single threaded and RPH will not yield for a call made via SHDN. Perhaps try using only one of the two for your project. 

I tried changing it so that drawMarker takes a GTA.Math.Vector3 instead of a Rage.Vector3 and then changed "target" in the callout that I am calling drawMarker from to be a GTA.Math.Vector3 but I'm getting the same error. Everything to do with drawMarker is now set up as being based off of GTA and nothing to do with rage but it still throws the error... Any ideas? I can't figure this out..

Are you loading your mod using RAGE Plugin Hook or SHDN?

I'm loading it with RagePluginHook. I made an LSPDFR Callout and inside of the "Process" method I am calling a separate class which takes nothing to do with RagePluginHook. This is because the DrawMarker() method is built into GTA and I can't find anything like it inside RagePluginHook. I'm not sure if I'm just not seeing it or if it really isn't possible to draw a marker through an LSPDFR callout.

I'm no expert but can't you just use Rage.Native.NativeFunction.Natives.DRAW_MARKER()?

When you say built into GTA, you are referring to SHDN I assume. Please note, that as I have stated before, it is unlikely that mixing RPH and SHDN will work. As will has pointed out, the safest option would be to either port the code to RPH or use natives there directly.

As far as I can tell Rage.Native.NativeFunction.Natives is a property of NativeFunction and doesn't have any methods in it.. am I missing something? I can't find the method anywhere.

It is a dynamic object, meaning for any name given it will try to resolve it as a native and call it. So Rage.Native.NativeFunction.Natives.DRAW_MARKER will attempt to invoke a native called DRAW_MARKER which is exactly what you need. Just need to supply the parameters.

Well I'm no longer receiving errors or crashes but in a way that's just more frustrating as the marker still won't appear... my new code reads as such: 

Spoiler

Rage.Native.NativeFunction.Natives.DRAW_MARKER(2, target.X, target.Y, target.Z, 0.0f, 0.0f, 0.0f, 180.0f, 0.0f, 0.0f, 0.75f, 0.75f, 0.75f, 204, 204, 0, 100, false, true, 2, false, false, false, false);

 

I still can't find the paramaters I'm supposed to use anywhere online, but I found one thread where someone used the code above (different x, y, z obviously) but it just wont work for some reason.

https://www.dev-c.com/nativedb/func/info/28477ec23d892089

 

Example that will spawn an amber rotating chevron over the character's head:

var player = Game.LocalPlayer.Character;
while (true)
{
    Rage.Native.NativeFunction.Natives.DRAW_MARKER(2, player.Position.X, player.Position.Y, player.Position.Z + 2f, 0f, 0f, 0f, 0f, 180f, 0f, 2f, 2f, 2f, 255, 128, 0, 50, false, false, 2, true, 0, 0, false);
    GameFiber.Yield();
}

Note it has to be called per tick.

I use a extension class specifically for markers. I can't remember where I found it , Was on google somewhere. I did look again but couldn't find the author. I take no credit for this class & if anyone knows who created it please let me know so I can credit them.

Thanks, forgive me but I'm still fairly new to programming, would you mind explaining how I would call this? Does it work like a method? Inside a callout how would I write the code that would tell this class to display a marker? Do I call it like a method like "Marker.Marker();"? Thanks alot for your help 🙂

First of all you would create a new class named say Marker.cs.
Put the code in that spoiler in there and rename to your namespace (where it says YourProjectName).
Then from that point in a callout you can use Marker1 = new Marker(); With your parameters.
Marker1.Visible = true;
