Unit Selection

Hi Guys,

Like in an RTS I'd like to render a circle around the base of a mesh when the user selects it. I've tried a billboard but they don't do the job. Would a decal work? And if so can someone point me in the direction of an example?

yes a decal could work.

point in the direction: place the decal or a simple mesh with a circle texture below the unit .... its very easy.

if you dont know how to do that, you should ask yourself if an rts-type game isnt a number too big for you

good luck & see you!

bye

what is a decal?

Guest · Post by **Guest** » Fri Dec 30, 2005 9:38 pm

Detail, game decorations...

Images layered over an already textured object. Like foorprints, the chip/burn marks left on a wall when shot with a bullet, or a selectable arm patch.

Yes, Irrlicht is able to do decals.

Thanks to Armen138 DecalSceneNodeClass everything is easy.
You have the link below to the full class:

Here you have some tutorials/advices:

I use Armen's class and Irrlicht 0.12 and it works excellent.
Here is a shot from my game:

Btw. My User interface and crosshair is purple isn't it ? I hope it is not pink, I think I have some problems with differing colors.

Dawasw, thats cool but I hope that means you will still work on lotr. Also the gui looks a little pink but it could but bright purple. Go a little darker and you should be fine. That is of course, if you insist on having it purple because it looks great as it is.

That is great with the decals!!!
But is there a way to get it worjing with only having a point and the normalvector? cause i'want to display the decal in free space and there are no triangels where i could attach it to.....i would need to get three points all on a plane.....i know how i could culculate that but the programm can't...lol

in this decal eksample a project specific headerfile, "time.h" is used- Does anyone have this file? (tutorial links are dead)

dawasw · Post by **dawasw** » Sun Jan 01, 2006 2:11 pm

Time.h should be included with your dev-cpp compiler. (I think it should be included in every c++ compiler

)

oh.. it is -that- header..?
i thought it was task specific because of its reference -eg

Code: Select all

"time.h" and not <time.h>..

ok, thanks -i'l try the default time.h and see if i can make it spin
