Unit Selection Indicator

[coder543]

Apart from me sitting down and making a green oval shaped mesh, does anyone know of a quick and easy way to indicate which units in an RTS i have selected, hopefully using a circle/oval shape?

I think there might be a way to do this using primitives, which would be cool.

Assume ISceneMeshNode* name of the unit is "current"

If anyone can provide code to do this, that would be amazing.

That won't help you much.
What problem do you have using primitives to draw this ?

I am experienced enough with the engines in use that I can make a fairly large amount of progress quickly, but I've learned this knowledge in a short amount of time. Because I learned it quickly, there are holes in my knowledge. One of them is primitive manipulation. I could (theoretically) look up the code in the documentation, but I am solving other issues as the moment such as the actual functionality behind the unit selection.

It would be nice to get that code, plus I would learn how primitives work from that code.

You could try to create a sphere and scale it wisely. When unit being selected, parent it to this node.

To indicate which units is selected i'd use emitting colors - i.e. change the material of the unit to have small amount of emitting color.

That is an interesting way to do it... right now I am turning whether or not the unit is affected by light on and off. I was hoping that it would be possible to draw a little circle around the units using primitives. See this http://www.playrage.com/wp-content/uplo ... aft3_3.jpg

Try some kind of volume light. A plain circle would just be a quad under the mesh with a circle texture on it, aligned to the up-vector of the mesh.
