Crosshair

[Guest]

Hello,
I'm new here and I have a question: how can I add a crosshair. Please send some code

PS: Please excuse my bad english

[LordNaikon]

for a solution of 1024x768

Code: Select all

driver->draw2DRectangle( irr::video::SColor(100,100,200,100), irr::core::rect<s32>(511,372,513,378) ); //above

driver->draw2DRectangle( irr::video::SColor(100,100,200,100), irr::core::rect<s32>(518,383,524,385) ); //right

driver->draw2DRectangle( irr::video::SColor(100,100,200,100), irr::core::rect<s32>(511,390,513,396) ); //down

driver->draw2DRectangle( irr::video::SColor(100,100,200,100), irr::core::rect<s32>(500,383,506,385) ); //left

looks like this

It works! Thanks

What you could also do, because you have to account for other screen sizes, if you want the cross hair in the middle of the screen, you can do something like:

Code: Select all

irr::core::position2d<irr::f32> pos = Cursor->getRelativePosition();
// keep cursor in the middle of the screen
pos.X = 0.5f;
pos.Y = 0.5f;
Cursor->setPosition(pos);

This will position the cursor in the middle of the screen.

[warui]

Why you get position of a cursor and then overwrite it with new valuse. To keep cursor in the meedle of the screen this is sufficient:

Code: Select all

Cursor->setPosition(irr::core::position2d<irr::f32>(0.5f,0.5f));

[Endar]

Oh, yeah, okay. That does make more sense.

I was just changing someone else's code, which generally I do on a mostly line by line basis, because its occasionally hard to see where someone is going with it. (occasionally, but admitedly not in this case )

If you use a camera that traps the cursor, it may jump around a bit more than you'd want a crosshair to. I haven't actually tried it, so maybe it wouldn't be a problem, but the cursor with the irrlicht fps camera appears to jump around a bit

Thanks to all,
I have one more question to LordNaikom: where did You get that shotgun? Any links?

[LordNaikon]

i know you would ask that question , but i have to say i don't know where i get that shotgun sry. i am also searching of free model stuff all around.

This'l add your crosshair no probs buddy....

Code: Select all

scene::ISceneNode* crosshair = 0;
   
      crosshair = smgr->addBillboardSceneNode(crosshair,   
      core::dimension2d<f32>(10, 10));
      crosshair->setMaterialFlag(video::EMF_LIGHTING, false);
      crosshair->setMaterialTexture(0, driver->getTexture 
                                               ("../../Textures/crosshair1.bmp"));   
      crosshair->setMaterialType(video::EMT_TRANSPARENT_ADD_COLOR);
      crosshair->setPosition(core::vector3df(0,0,150));
   
      camera->addChild(crosshair);

sorry mate but this thread is a _little_ old (lets say 1,5 years) - the thread owner will have found the solution already after such a long time i guess

see you!

[independentCreations]

must of went diggin for that 1 th3one, year and a half. i hope guest solved this allready

[Th3one]

hehe yea...but surely it'll help the likes of me that were searching for the solution

[magisterrivus]

A little addition to this 2yrs old code

Code: Select all

crosshair->setMaterialFlag(video::EMF_ZBUFFER, false);
