:D thanks for the answer

the problem is this:

i have two points: vector3df(x1,y1,z1) and vector3df(x2,y2,z2)
for example the line that connects these two points is long 200px. Now i need to find the end point of the line that starts in vector3df(x1,y1,z1), point to vector3df(x2,y2,z2) and is long ...

i have a line with the start and the end point. I need to reduce the length of 40px. How? Thanks

i have created a node for the water as in the tutorial

IAnimatedMesh* mesh = smgr->addHillPlaneMesh( "water",dimension2d<f32>(75,75),dimension2d<u32>(40,40), 0, 0,dimension2d<f32>(0,0),dimension2d<f32>(25,25));
ISceneNode* node = smgr->addWaterSurfaceSceneNode(mesh->getMesh(0), 3.0f, 300.0f, 30 ...

but EAAM_OFF don't mean that it is disabled? i must change this row with what? mat.AntiAliasing=video::DISABLED?

thanks for the help

SMaterial mat;
driver->setMaterial(mat);
mat.Thickness=10;
mat.setTexture(0, 0);
mat.Lighting = false;
mat.AntiAliasing=video::EAAM_OFF;
driver->draw2DRectangleOutline(rect< s32 >(263,673,314,681),SColor(255, 255, 255, 255));


:? the problem is the same. I have set the thickness to 10 ...

Simply set the anti-aliasing settings in the 2d render mode method to disabled.

I'm sorry but i can't find the correct parameter, what is the function?

my version is the 1.6, the last. the video driver is the opengl. It is sufficient to change the video driver? What type of video driver is the best in this case?

i have placed this function in the main loop:

driver->draw2DRectangleOutline(rect< s32 >(263,650,415,658),SColor(255, 255, 255, 255));

I don't understand why, during the execution, it changes thickness from 1 to 2 pixels

the problem is that the function is called one time... any ideas?

i want to set the visibility of a node after 2 seconds, is possible? (the program mustn't be stopped, therefore no sleep... )

what is the simplest way to print an accent? ascii?

the code for 'é' is 8a, but if i print \x8a don't works

i have created an array of enemies:

enemy.push_back(smgr->addAnimatedMeshSceneNode(smgr->getMesh("../../media/ninja.b3d")));

and when i kill an enemy i delete the enemy with this:

enemy.erase(i);

but why the enemy don't disappear? it is normal?

ok i have understood thanks

well, if i create ray2 with the first parameter different by i, it works but, why they point to the same poisition? they are different array...
I can create the same function with a different structure?
for example with array<line3df>ray i can create a multiple array?

i'm sorry but i believe that i haven't understood, in the first post with the 'for' for each enemy there are:

ray[0],ray[1],ray[2],ray[3].

i don't allocate ray[0][4]. In fact the first example works, is the second that don't works...
