aiGetMaterialFloat() not working? (C)

[Luan]

Adding this to my code:

float f = 1.0f;
aiGetMaterialFloat(mat, AI_MATKEY_SHININESS, &f);

results in:

gcc src/*.c examples/game.c -o bin/game.o -lGL -lGLEW -lSDL2 -lSDL2_image -lassimp -lm

  aiGetMaterialFloat(mat, AI_MATKEY_SHININESS, &f);

mat is of type struct aiMaterial*. What am I doing wrong?

Hi,

I used another function, witih 4 parameter and works well.

float specularPower = 0.0f;
int max;
aiGetMaterialFloatArray(material, AI_MATKEY_SHININESS, &specularPower, &max);
