SDL Mob Class

[N36fSL3A]

How would I make Mobs from this code? I know I can use vectors but how would that make every single Mob react to colision, death, etc? I know I can code functions to do that but how will the vector use my functions?

Here's my code

#ifndef _KYDEN_MOB_H_
#define _KYDEN_MOB_H_

#include <string>

class Mob
{
	public:
		//Functions
		virtual Mob();
		void MobisHit;
		virtual void MobStrike(bool MobisAttacking);
		virtual void MobUseItem(bool MobisHoldingItem, X, Y,);

	protected:
		//Interger Variables

		//Doubles & Float Variables
		float Mob X;
		float Mob Y;
		float MobHealth;
		float MobAttack;
		float MobDefense;
		double MobSpeed;

		//Boolean Variables
		bool MobisHostile;
		bool MobisDead;
		bool MobisAttacking;
		bool MobisHit;
		bool MobisHoldingItem;
		bool MobisInMotion;
		
		//String Variables
		std::string MobName;
		std::string Mob

		//SDL_Surfaces
		SDL_Surface* MobImage;
};

#endif

Mob Watts;

every single Mob you declare is its own entity.

Can a Mod remove this? I'm going to post this in Beginner Fourms. If not someone please HELP ME!!!

You can use a loop to iterate through all the Mobs in the vector and for each Mob you do whatever it is you want to do.

[N36fSL3A]

Peter can you give me an example?

[Peter87]

Ok. I don't know how your game is supposed to work but say that you are storing your Mobs in a vector.
std::vector<Mob> mobs

If Mob has a function update() that updates the mod. It could be updating the position, velocity, making decisions and such things. To call the update() function on all mobs you can use a loop.

for (std::size_t i = 0; i < mobs.size(); ++i)
{
	mobs[i].update();
}

If you want to do collision detection and call the MobIsHit() function when the Mob is colliding with another Mob, and you have a function isColliding that returns true if the two Mobs passed to it is colliding, you can use a nested loop to check every mob against each other.

for (std::size_t i = 0; i < mobs.size(); ++i)
{
	for (std::size_t j = i + 1; j < mobs.size(); ++j)
	{
		if (isColliding(mobs[i], mobs[j]))
		{
			mobs[i].MobIsHit();
			mobs[j].MobIsHit();
		}
	}
}

But I'm going to use Polymorphism, this is the base class, so would this be a virutal Functon

[pogrady]

It can be, but if each derived object from base class Mob behaves in the same way, then there is no reason too.

[Peter87]

In that case you will have to store pointers in the vector std::vector<Mob*> mobs;. You can also use smart pointers if you know how they work. Which functions to be virtual is up to you.

Thanks, I'll test out the concept later when I get home from school.
