Need Help, I'm new to Irrlight

[CodeDragon]

Hello,
I'm CodeDragon and am new to game development.

I have a few questions:

- How can I make players hit each other with guns etc.. , How can I check if the bullit (Which is in the air) hits him/her.

- How can I make a good map?

- How can I store textures in a variable for pre-loading?

- How can I store my player details? (Is the next code ok or not?)

Code: Select all

#ifndef PLAYER_H 
#define PLAYER_H 
#include <irrlicht.h>
#include "Weapon.h"
#include "Inventory.h"

#define MaxPlayers 16

struct sVector
{
	float X;
	float Y;
	float Z;
};

class cPlayer
{
private:
public:
	sVector Recoil;
	sVector Location;

	BYTE iLife;
	BYTE pTeam;

	pWeapon CurrentWeapon;
};

#endif

- And how can I make pickup marks like this:



That is points to the camera.


Thanks for helping if you do.

Read every tutorial and you'll learn everything that you have just asked for.
Everything except the "make good map" part, you need to know how to model in order to make a good map.
You shouldn't need to worry about maps at first I think, you can make them when you'll have your game engine running

You should start by making small demos with each feature instead of trying to make complete game.

Get comfortable with the engine and then start coding.

And again Read all of the tutorials carefully

Hello CodeDragon,

I have a few questions:

- How can I make players hit each other with guns etc.. , How can I check if the bullit (Which is in the air) hits him/her.

Usually you use trace-lines for that. Which means you check a line for collisions that starts from your gun and has a certain length (just any large enough value) in the direction of your gun. Check example 07 for how to do collisions.

- How can I make a good map?

The most common way is to use some map-editor. A simple editor is for example irrEdit, but there are also other editors which might work. Or you might write your own map-editor (for larger games that's often a good idea as you can easier do game-specific stuff in your editor then). An alternative is sometimes to model your whole level in a 3D Modeling application (like Blender). Or any kind of mixture - doing most stuff in Blender and the rest in irrEdit.

- How can I store textures in a variable for pre-loading?

Irrlicht automatically does cache textures when they are loaded.

- How can I store my player details? (Is the next code ok or not?)

Code: Select all

#ifndef PLAYER_H 
#define PLAYER_H 
#include <irrlicht.h>
#include "Weapon.h"
#include "Inventory.h"

#define MaxPlayers 16

struct sVector
{
	float X;
	float Y;
	float Z;
};

class cPlayer
{
private:
public:
	sVector Recoil;
	sVector Location;

	BYTE iLife;
	BYTE pTeam;

	pWeapon CurrentWeapon;
};

#endif

It is your code - so you can code any way you want as long as it works. Although not everyone might like your style. For example in my case I dislike a few parts:
- Using an own vector class when Irrlicht already has one.
- Using BYTE (very MS-specific style, no real gain)
- pWeapon sounds like you typedef'ed a pointer - something I've seen a few times. I think it makes the code harder to read as you no longer see on first view if it's a pointer like a * clearly shows. (also see http://marc.info/?l=openbsd-cvs&m=117270339530912).

- And how can I make pickup marks like this:



That is points to the camera.

Usually it's simply a 3D Node. Sometimes a Billboard (Images that always look towards the camera, see IBillboardSceneNode). And then it checks for collision with the player - so when you run over it, it gets picked up.
