Rendering Objects On Canvas

Hey all. I am trying to simply have a mesh object displayed on the screen like how 1st person weapons work but within a HUD window. I have a bad or missing expression when trying to spawn the mesh:

Code: Select all
class TestMesh extends AlarmUnit;

var Canvas canvas;
var SummerPlayer PlayerOwner;
var Inventory inventory;

function GoOnScreen()

local rotator NewRot;

PlayerOwner = SummerPlayer(GetPlayerPawn());
   Self.SetLocation( PlayerOwner.Location + CalcDrawOffset());
   NewRot = PlayerOwner.ViewRotation;

   Canvas.DrawActor(Self, false);

simulated function vector CalcDrawOffset()
local vector DrawOffset, WeaponBob;
DrawOffset = ((0.9/PlayerOwner.FOVAngle * inventory.PlayerViewOffset) >> PlayerOwner.ViewRotation);
DrawOffset += (PlayerOwner.EyeHeight * vect(0,0,1));
return DrawOffset;
   ItemName="Testing Mesh"

The window spawns this object and calls the PutOnScreen function but the object spawns in the world and not on the canvas.

Please help. Thanks.

It should be Spawn(class'AlarmUnit') not Spawn(class<AlarmUnit>).

Thanks Poor! Updated the code. The alarm unit spawns but not on the canvas :/

You declared a Canvas variable but you didn't assign anything to it. It will be null and you'll get access nones. I don't see what is calling GoOnScreen() either.

It looks like you are trying to have an alarm unit on the players screen. A texture would work better than an actor. But if you are trying actors then you should set all the collision and blocking variables to false so it can move freely.

I believe you have to use a Window to properly use DrawActor. AugmentationDisplayWindow shows how DrawActor is used for the vision aug.

Initially I tried textures but rotating GUI in UE1 is impossible. So I thought "How about rendering a rotating actor?". Thanks for the help. I was trying to use the same method weapons use to render animated/moving actors on the screen so I can have rotating UI at some point.
