Is it possible to create a RTS camera, like in Starcraft II etc?

objo wrote at 2012-01-03 19:55:

sorry, I have no experience with Starcraft or any other real time strategy games, so I don't know what is needed. Do you need camera translation by WASD keys?

can this link help (from irrlicht 3d)? http://www.irrlicht3d.org/wiki/index.php?n=Main.RTSCameraByCmdKewin

Yeah, basically the feature set of the linked camera is what I need.

• No vertical translation 
• Translates with WASD keys, (right mouse button and arrow keys) 
• Translates with mouse movement on border screen. Left, Right, Up and Down 
• Zooms with wheel (and right-left mouse buttons) 
• Ability to recenter itself around a node
• define min and max zoom levels
• define boundaries for translation so it does not translate outside the map.

I put not so important stuff in brackets. Is this possible to realize with the Helix 3D Toolkit?

Thanks.

This should be included in the 'walkaround' camera mode - I have not tested it after latest camera control refactorings, might need some updates...

I am attempting to code a RotateManipulator in C# codebehind (not xaml) to add rotateable and translateable planes on a double click event.

How would this line from ManipulatorDemo / MainWindow.xaml line 185 be coded in c#?

<ht:RotateManipulator Color="Blue" Axis="0,0,1" Transform="{Binding Transform, ElementName=plane2}" TargetTransform="{Binding Transform, ElementName=plane2}" Diameter="1"/>

It is the syntax of the binding transforms that I am struggling with (I am new to wpf if you haven't guessed)

Thanks! badgerbadger.

use the SetBinding method

Thanks, I had been using that but not getting it to work. Attempted to code ManipulatorDemo / MainWindow.xaml line 185 as

var plane = new RectangleVisual3D();

plane. etc

var manip = new RotateManipulator();

...

BindingOperations.SetBinding(manip, RotateManipulator.TransformProperty, new Binding("Transform") { ElementName = "plane" });
BindingOperations.SetBinding(manip, RotateManipulator.TargetTransformProperty, new Binding("Transform") { ElementName = "plane" });

and other combinations of setBinding but get "System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=plane'"...

Apologies if this is a newbie wpf error but not finding much relevant on the web

Hello.

I need to add labels to objects, for example, to sign the top of the cube.

Like this: https://dl.dropbox.com/u/22892769/screen.PNG

How can I do that? Thanks.

Hey Objo. I'm trying to change the center of a SphereVisual3D object and make it a 2D object by setting the Z parameter to 0. The problem is it won't flatten the sphere. Is there any way to do this? Or is there any other way to make a 2D filled in circle using your toolkit? Thanks. Here's my code:

private void Mouse_Down(object sender, MouseButtonEventArgs e)
{
     lineOne = (Point3D)GetPoints(e);
}

private void Mouse_Up(object sender, MouseButtonEventArgs e)
{
     lineTwo = (Point3D)GetPoints(e);
     SphereVisual3D sphere = new SphereVisual3D();
     sphere.Center = new Point3D((lineOne.X + lineTwo.X) / 2, (lineOne.Y + lineTwo.Y) / 2, 0);
     sphere.Radius = Math.Abs(lineOne.X - lineTwo.X) / 2;
     viewport.Children.Add(sphere);
}

Try a ScaleTransform3D(1,1,0). I am not sure it will look good, but it should flatten the sphere..

I have a couple of questions.

1. Why does the ModelViewer example app use ModelVisual3D instead of HelixVisual3D?

2. I would like to load up 2 models into a HelixViewport3D, and use a slider to change opacity between the 2, for comparison purposes.  I would have to use a switch to manipulate 1 model at a time.  Any thoughts as to the best way to accomplish this?

Thanks,

Paul

1. Use ModelVisual3D to show models loaded from the supported file formats, use HelixVisual3D to show 3D helix models.

2. I suggest you use DiffuseMaterials on your models, and bind the opacity property of the brushes
