Interaction with a 3D Cube

[Bukue]

I?m developing a webpage where it has to be a 3D cube, and each of its faces
has to point to a different URL. I have already constructed and shaded the
cube. I have also coded the part of the rotation of the cube. But I still not
find the part where the click on a certain face lead me to a specified URL.

I wrote this code in order to find the way to know wich face has been clicked:




************************************************** ******************************
************************************************** *

on mouseUp me
returnData = member("3D").camera[1].modelsUnderLoc(the mouseLoc,#detailed)
member("TXTcara").text = "You clicked on face " && returnData[1].faceID
end


************************************************** ******************************
*************************************************
where TXTcara is a textfield on the stage where I print which face has been
clicked



But it always says me that I clicked on face 1 or face 2. I mean a cube has 6
faces... and this code says that it has only two!!

How can I cerainly know wich face has been clicked??

The cube was constructed as a box.

the face is the polygon and not the face of the cube.
if you use the built-in modelresource than each face of the cube has a
seperate shader (look at the models shaderlist). I am pretty sure, you will
assign different shaders to the different clickable cube faces. so you will
need to get the shader which was clicked on.
this information is the #meshID of the picking data which is returned by the
picking functions (modelunderloc and modelunderray), if set to #detailed.

so in your case:

on mouseUp me
returnData = member("3D").camera[1].modelsUnderLoc(the mouseLoc,#detailed)
member("TXTcara").text = "You clicked on face " && returnData[1].meshID
end



I guess your snippet is a fast sample to point out the problem, but just in
case...you should check, if a model was hit in the first place and often the
above behavior is on the 3-D sprite and if you have only one camera you could
get away with all the hardcode (member name, camera index etc.) with:

on mouseUp me
sp = sprite(me.spritenum)
ml = the mouseLoc - point(sp.left, sp.top)
cam = sp.camera
returnData = cam.modelsUnderLoc(ml, #detailed)
if count(returnData) > 0 then member("TXTcara").text = "You clicked on face
" && returnData[1].meshID
end

Thank you very much!! It works perfect!! =D
