Hi, I've been trying to create a portal affect similar to what is seen in the game Narbacular Drop (And Prey it seems) whereby there are two portals and as you look out of one you see whats on the other side of the other. I haven't done very well. I've been looking at the tech docs for the game and ...

For arraySize you could just do: sizeof(TriangleDatas) But this would only work if you gave TriangleDatas a size i.e. triangle3df TriangleDatas[99]; As for triangle3df I guess it's a vector and you should be able to access the data you want like you would any other data structure: triangle3df.X tria...

Hmm not sure whether this would cause linker errors but in your child class you only need to include "ILoadedMesh.hpp" as in that file it also includes the other two. So essentially you're including the same files twice. Could you post the errors you are receiving? That might help.

OK Turns out I was debugging the wrong section of code. I've located the real trouble. Sorry about that

I think you are right. I just replaced the function contents with this: int x; x = 0; return x; With the same crash. This is how I'm calling the function: int elementNo; elementNo = this->getElementNoFromName(onSelectName); It is being called from within another function which belongs to the same cl...

OK It seems it doesn't work now if I replace return i with return 0 or any other number.

getName() simply returns a value in the cMenuElements class which is what m_elements[] is. The else statement is just a remnant from a previous incarnation of the function so I just left it there as it's no cause of a problem. I'm not sure if xstring might be related to std::string in any way?

Are you sure Red is the right colour? Nice effect though

It doesn't reach those in the tests I'm doing. The function will break from that loop as soon as it finds a match for the string provided and in the tests I'm doing m_elements[0] is that match.

No, I've done debugging and m_elements[0] is definatly a valid pointer. If it wasn't surely it would not like the line where I compare the two strings? Anyway it is valid as this is an excerpt from a menu system I'm writing and it gets set through the menu file which has all worked up until now when...

int cMenu::getElementNoFromName(std::string name) { int i; for(i = 0; i < 20; i++) { if(m_elements[i]->getName() == name) break; else continue; } return i; } For some reason this function will crash on the return i line with this error: Unhandled exception at 0x1048c1fe (msvcp80d.dll) in Metal Gear...

I'll try making my logo Image a size that is a power of 2. How can I tell IGUIImage to only display part of it?

OK So I know I can't use textures that are not a square size i.e. 512 x 512 etc. So what if I want to display a logo which is 500 x 200 or something short of splitting it up into several square textures? I'm using IGUIImage to display 2D images on the screen.

You need to apply a Collision Animator to the camera using the second TriangleSelector.

Well first you need to create a Triangle Sleecter for your mesh: scene::ITriangleSelector* selector = 0; selector = smgr->createOctTreeTriangleSelector(levelmesh->getMesh(0), levelnode, 128); levelnode->setTriangleSelector(selector); selector->drop(); Then you need to apply a Collision Animator to w...
