Added prototype:
Code:
void movePlayer();


Code:
#include <acknex.h>

void doSomething (ENTITY* ent);
void movePlayer();

void main()

	warn_level = 6;
	fps_max = 60;
	d3d_lines = 3;
	level_load(NULL);
	camera.x = -96;
	ENTITY* ent=ent_create(CUBE_MDL,nullvector,NULL);
	ENTITY* entTerrain = ent_createterrain(NULL, vector(0, 0, -20), 45, 45, 100);
	
	doSomething(ent);
}

void doSomething (ENTITY* ent)
{
	player = ent;
	

	while(1)
	{
		ent.pan+=time_step;
		vec_fill(ent.scale_x, 0.1 + abs(2 * sinv(ent.pan)));
		c_setminmax(ent);
		vec_set(sky_color,vector(random(255),random(255),random(255)));
		ent.z+=random(ent.scale_x*2)-ent.scale_x;
		wait(2+floor(random(10)));
	}
}

void deformTerrain(ENTITY* ent)
{

void movePlayer()
{
	VECTOR speed;
	speed.y = (key_a - key_d) * 3 * time_step;
}
