Class member function not recognized??
Hi everybody, recently I've been working on getting a simple gravity program where a spaceship orbits around a sun going, I've almost completed it but I've hit a roadblock.
Whenever I compile it says
13 C:\Dev-Cpp\Mission Space rev2\C-SpaceShip.cpp expected `;' before '(' token
and that
29 C:\Dev-Cpp\Mission Space rev2\Body.cpp 'class SpaceShip' has no member named 'Update'
I know it something very simple that's wrong with the function Update in my class, can anyone help me figure it out?
Code:
#include "math.h"
class SpaceShip
{
public:
long int mass;
int locX;
int locY;
int imageheight;
int imagewidth;
long int velocityX;
long int velocityY;
SDL_Rect dest, source;
int Update (Planet *pEarth, SDL_Surface *Red, SDL_Surface *screen)
{
int distance;
int forceX;
int forceY;
long int masses;
long int GravVector;
long int accelX;
long int accelY;
distance = sqrt(((*pEarth.dest.x - locX * *pEarth.dest.x - locX) + (*pEarth.dest.y - locY * *pEarth.dest.y - locY))); // this is the distance formula
forceX = distance * distance;//these lines are used to square distance
distance = forceX;//this is also
forceX = 0;//this is the last one
masses = (*pEarth.mass * mass);
GravVector = masses/distance;//distance is already squared here
forceX = GravVector/(*pEarth.dest.x - locX);//normalizes vector into x and y forces instead of vector force, GravVector is a force.
forceY = GravVector/(*pEarth.dest.y - locY);
accelX = forceX/mass;
accelY = forceY/mass;
velocityX = velocityX + accelX;//velocity is part of class data not definded in this function
velocityY = velocityY + accelY;
dest.x = dest.x + velocityX;
dest.y = dest.y + velocityY;
BlitSurface(Red,source,screen,dest);
SDL_UpdateRect(dest.x,dest.y,dest.w,dest.h);
return 0;
};
SpaceShip(int parmass, int locationX, int locationY, int parimageW, int parimageH )
{
velocityX = 0;
velocityY = 0;
mass = parmass;
locY = locationY;
locX = locationX;
imageheight = parimageH;
imagewidth = parimageW;
dest.x = locX;
dest.y = locY;
dest.h = imageheight;
dest.w = imagewidth;
source.x = 0;
source.y = 0;
source.h = imageheight;
source.w = imagewidth;
return;
}
};//end of class
