I want to check if an NPC is on the ground.

I am using the following code to get the positions of the headbone and the ground shown on the screen:

char c[40];
char c2[40];
float act = 1;
float act2 = 1;
std::string text = "Zcoord ground = ";
std::string text2 = "Zcoord head = ";

Vector3 vechead = ENTITY::GET_WORLD_POSITION_OF_ENTITY_BONE(playerPed, 21030);
float groundzcoord;
GAMEPLAY::GET_GROUND_Z_FOR_3D_COORD(vechead.x, vechead.y, vechead.z, &groundzcoord, true);
act = groundzcoord;
text = "Zcoord ground = " + std::to_string(act);
act2 = vechead.z;
text2 = "Zcoord head = " + std::to_string(act2);
strcpy(c, text.c_str());
strcpy(c2, text2.c_str());
DrawText(0.4, 0.4, c);
DrawText(0.3, 0.3, c2);

 

Unfortunately both values seem to be always 0:

 

 

Can someone hint me in the right direction, please?

How can I get the z coordinate of the skull (bone ID should be 21030) and from the ground?

 

 

Edit: here is the line of code that needed correcting:

 

Vector3 vechead = ENTITY::GET_WORLD_POSITION_OF_ENTITY_BONE(playerPed, PED::GET_PED_BONE_INDEX(playerPed, 21030));

Ah, that would have probably saved me a lot of trouble lol
