Irrlicht Engine

thanks trivtn

Before anyone tells me to search the forums, i have, and everything i've found is either out of date (irrlicht 1.2 and below) or irrelevant, or is someone asking just like me and not getting an answer, or has a solution that just doesn't work.I've looked into the IcameraScenenodeFPS and tried to ...

1. You can use the ISceneCollisionManager::getRayFromScreenCoordinates() method along with the ICursorControl::getPosition() functions to get a line from the camera through the mouse cursor.


i tried using the following code :


core::line3d<f32> line;
core::position2df RightMousePosition(RvX ...

i tried modding that code, and placing it under my mouse movement event handler as follows :

Global Declarations to make my life easier

const f32 MAX_VERTICAL_ANGLE = 88.0f;
const f32 RotateSpeed=100;
const f32 MoveSpeed=100;


Under the mouse movement function:


const u32 camIsMe = smgr ...

i'm trying to use the position of an on screen cursor instead of the center of the screen for collision, the code i'm using (Based on what i understood from graphics programming is as follows) note that ms->pt.x and ms->pt.y is a custom input event handler code to point out where the mouse cursor is ...

No, don't........
what the... Omar, stop trying to help if you're not sure, you'll only confuse ppl more.
If he does that his camera will ALWAYS look in the same direction.

anyway, look for this section.
It teaches how to rotate a vector based on orientation.
Based on that, do your rotation bit ...

i'm trying to make the camera move around like an fps cam, (the code omar gave me above didn't work);

tell me, what is wrong with this code;
ms->pt.x
and ms->pt.y
are the x, y positions of a mouse cursor on screen... regardless i think if it's a fps camera, then i shouldn't need to use the edges of ...

i don't know about 1,2 and 3

but the easiest way to do the sound thing, is to use Irrklang

and just use the audioplay function to play that sound file whenever you pretty that button.

such that :



case KEY_KEY_T:
{
Audioengine->play2D("hello.wav"); }


Check the irrklang tutorials

thanks

1- the main problem with point number 1 is i have 2 cursors on screen, not one....

4- so i should make a thin lazer line as a billboard?

btw, is it at all possible to explain to me how to make a custom camera using a custom event handler (not irrlicht based) , no one seems to know...

are x, y and z relative?

i mean changing the camera like that, wouldn't move me forward or backwards or left and right right?

instead it would change my position inside the envirnoment right?

or are they relative?

1- I know through the tutorials, that the code to collide with an enemy using a normal fps camera is basically using this

core::line3d<f32> line;
line.start = camera->getPosition();
line.end = line.start + (camera->getTarget() - line.start).normalize() * 1000.0f;


thing is, my virtual lines ...

i've tried it out, after fixing the syntax errors, and it doesn't really work, i don't understand why... regardless, thanks for the help.


Alf shokr ya me3alem

thanks for the reply, but can you tell me what variable type cpos is initilized as?

and should that code (or what's similar to it) be inside the event handler itself , or the jump=true part be inside the handler, and the rest inside the draw loop itself?

(just incase this makes a difference, im ...

my friend, i am well beyond the point of reading the first tutorial... i've looked through it again in case there's something i overlooked, but i meant making a fps camera jump, not a model jump.

if you mean the api, i've been looking for hours, can't find anything useful , mind linking it?

i maybe overworked and that's why i may have overlooked something, but i'm not a forum noob, i usually do a search before i ask any questions, and only ask questions when i can't find anything.
much ...
