Crosshair help

[Gameswhiz]

Hi,

This is my first post so be gentle.I am creating a little demo thing to see what I can do in irrlicht and I decided on a first person shooter where you just have one level, two guys and you control one and you shoot each other.I was thinking about the crosshair and I was wondering if I could use a billboard to make the crosshair? What do you think?
Thanks,

Alex

Why not just draw a 2Dpic in the middle, or where ever the crosshair is supposed to be

So is there a way to change the cursor using a bitmap image like make it a + instead of an arrow or is this not possible? Also should I use a billboard for the weapon(s)?

3-4 days ago I asked exactly the same. You have to make your weapon child of the camera and then place it good.

Code: Select all

scene::ICameraSceneNode* camera = sm->addCameraSceneNodeFPS(); 
scene::IAnimatedMesh* weaponMesh;
scene::IAnimatedMeshSceneNode* weaponNode;
weaponMesh = sm->getMesh("ak47.x");  //Your Mesh is loaded here
weaponNode = sm->addAnimatedMeshSceneNode(weaponMesh, camera, -1);  //optionaly here, you could set the initial pos, rot, and scale in that order 

// Your animation speed may be different so play with the value
weaponNode->setAnimationSpeed(20);

// The next few lines are the ones that have to be hand 
// tweaked and you may not at first see your weapon.
// The values below reflect my weapon setting to see
// it in front of me. My weapon had to be rotated 180
// degrees as thats how I modeled it and didnt want
// to rerig it and reanimate it.
weaponNode->setScale(core::vector3df(14,14,14));
weaponNode->setPosition(core::vector3df(15,-10,30));
weaponNode->setRotation(core::vector3df(180,0,180)); 

A little note: creating a game is a lot harder than it seems, even a demo

Thanks for that I'll be able to do it now.I guess I can have some fun now with my shotgun model and the homer simpson model I got from polycount heh.I'll see you guys around and thanks for the help.

What file format is the shotgun model?

[Gameswhiz]

All the models that I use are in the md2 format.

This is code I use to draw simple crosshair in my demo:

Code: Select all

driver->draw2DRectangle( irr::video::SColor(100,255,100,100), irr::core::rect<s32>(300,299,500,301) );
      driver->draw2DRectangle( irr::video::SColor(100,255,100,100), irr::core::rect<s32>(399,200,401,400) );

Really is that all the code you needed to add? Just draw to rectangls? Seems too easy really.

it is easy

for example for a new cursor:
core::position2d<s32> m = device->getCursorControl()->getPosition();
driver->draw2DImage (cursor, core::position2d<s32>(m.X,m.Y), core::rect<s32>(0,0,64,64), 0, video::SColor(255,255,255,255), true);

is pretty much all you need (of course you have to hide the original cursor and load a texture for cursor

If you find it too easy you can always do it in more complicated way

This is code I use to draw simple crosshair in my demo:

code:
--------------------------------------------------------------------------------
driver->draw2DRectangle( irr::video::SColor(100,255,100,100), irr::core::rect<s32>(300,299,500,301) );
driver->draw2DRectangle( irr::video::SColor(100,255,100,100), irr::core::rect<s32>(399,200,401,400) );

Hi, I got the crosshair in the middle using draw2DRectangle but how do I resize the rectangle? Also I am still have trouble rendering the gun infront of the camera all the time.I have created the node and loaded the mesh and texture but now what?

[Gameswhiz]

no one knows the answer? I really need this to get my project back on track.I just wanna know how to make a node the child of another node and how to change the size of a rectangle in the function draw2DRectangle().
Thanks,
Alex

I learned this from other guys on this forum and they are so right: http://irrlicht.sourceforge.net/docu/index.html

[Gameswhiz]

Code: Select all

driver->draw2DLine(position2d<320>, position2d<330>);

It could be a dumb question but does anyone know what is wrong with that?
