how i can set color to some ISceneNode objects ?
how i can set texture size (not rect size,size of texture on objects) ?

and how i can create some standart objects on irrlicht ? (sphere,piramyde and other)

afaik you can only change color with a different texture (e.g. blue/red/.. texture

the texture size on objects are saved and modified using a Modelling / Mapping Program, you can only create different kinds of planar mapping on
runtime and change the scale of the detailmap from an ITerrainSceneNode

the only "standard object" in irrlicht is a box, smgr->addTestSceneNode(..)

1. how to set material colors:

2. look at makePlanarTextureMapping, that way you can "scale" the textures of "objects" (nodes) i think thats what you are looking for.

3. you can create a custom scene node and add default models yourself, otherwise you just have, like master said, a testSceneNode

good luck!

for standart objects on irrlicht:
Emil Halim have made a class for IRR primitives

i have a problem with cpp

how i can read variables (int, float and other) use fgetc ?

ok... i can read int
but how i should read float ?!

Code: Select all

....
int FILE_read_int(FILE * file)
{
return fgetc(file)+fgetc(file)*256+fgetc(file)*256*256+fgetc(file)*256*256*256;
}
.....

void main()
{
....


FILE *file;
file = fopen( file_name, "r" );

int a1;
a1=FILE_read_int(file);

........
}

try fscanf, its like reverse fprintf:

Code: Select all

fscanf(file, "%f", &floating_point_var);

Note that you need to pass the address of a variable (using the & operator)

Code: Select all

	FILE *file;
	file = fopen( file_name, "r" );

	float zz;
	zz=110;
	
	fscanf(file, "%f", &zz);

in file :
CD 4C 9A 44
(in float - 1234.4)

what i doing wrong ?
