Space Onslaught

Space Onslaught is a game developed as a pair with a classmate, written in C++. Before this I had not spent much time in the land of C++. However, I did spend a sizable amount of time in C during my undergrad studies, learning about pointers and such. This is a 2 player local multiplayer game where both players shoot each other with a ton of bullets and each ship has 3 hits they can take before they get destroyed and lose the game. Each ship has 2 firing modes, a slower but wider shot, and a faster but more focused shot.

Example of the ships shooting and being damaged

Shooting

For my part on the project, I created the shooting for both weapons and helped with the bullet collisions. Each spread has 5 total bullets, and each bullet has an x and y direction that is normalized to keep the speeds the same. Every bullet is then updated to a new position using delta time and a speed variable that each bullet shares.

//update the bullet's position based on the slope given to the bullet
void Bullet::Update(float deltaTime)
{

	if (shouldUpdate)
	{
		//dividing by the entire slope normalizes so the value of the angle 
               //doesn't effect the speed due to the magnitude
		float xPos = GetPosX(), yPos = GetPosY();
		float xUp = (xSlope / (fabs(xSlope) + fabs(ySlope)));
		float yUp = (ySlope / (fabs(xSlope) + fabs(ySlope)));

		//add to the x and y positions using the slope values and 
               //modify them by the speed
		xPos += ((xUp) * (deltaTime / 100.f) * speed); 
		yPos += ((yUp) * (deltaTime / 100.f) * speed);

		setPosition(xPos, yPos);
	}
