Is there something that allows me to use the mouse to rotate the screen around based on the point that the mouse is at?

Like rotate around the position of the mouse, so I'm always looking at the mouse/center.

Basically, it would make the mouse the center of my screen.

If anyone has ever played an RTS you would understand this.

Can you explain it better?

I understand to things from you question:

1-Rotate from mouse position
2-Rotate from center of the screen (like in RTS).

When you say Basically, it would make the mouse the center of my screen I really don't get which of the two you want.

[center][center]

This should do the trick (*this is psuedocode, so don't copy and paste - obviously won't compile* ):

It will rotate the screen as if the mouse was the center.

A little more explanation would be nice

Rei - What Willie came up with is just perfect. You just need to translate it.












If you have a problem and want to make a task, then write down with your own words what you want. Try to split it up in parts as much as possible still not using any command but just your own words.

When you have the description then you can start to code the parts in it. You can't just sit and write on your keyboard and then suddenly have a game. I have been there and now Im using weeks for making description for just small programs just to be sure that I have everything

To be honest, if you aren't able to handle a simple task like camera rotation, I'm not quite sure you're ready to write a game, especially in C++. If the game is at all complex, you'll be needing to write MUCH more complex algorithms than this in the future. A good idea would be to write a bunch of small apps, each tackeling a particular task you want to learn, and once you have a good base knowledge, begin on the design/tech docs for a game. A word of advice (for anyone): don't even open the IDE until you've got a solid design/tech doc ready. Believe me, it'll make coding MUCH MUCH faster, you'll stay more focused on the task at hand, you'll discover issues that need to be resolved beforehand, and most importantly, the project will feel like a single unit as opposed to a bunch of small "chunks" forced together, which is what most end up being. Another piece of advice, don't hard code values. Figure out (beforehand) a system in which to assign the values, whether it be through #define macros (not best solution), files, whatever. This allows your app to be flexible and easier to debug/test. Remember: the more flexible your app is, the less likely it is to break in different situations. Plus, this makes overcoming limitations/breaks a lot easier later on. The moral of the story: "Plan for the future!" and "An ounce of prevention is worth a pound (more like a ton) of cure."

This is confusing, I see your other source code an some of it is pretty nice. Other than your invalid address problem with your arrays.

I think the problem is, you are not "reading" the actual help docs or attempting to learn what each of the parameters mean and what they are required for.

I think you should be more worried about doing small individual projects rather than coding a full game atm.

You are progressing fairly well, dont get me wrong. Just some CC.

-_- I'm not coding a game pples. I'm making a rough one level demo that can get me an A in my Game and Simulation Programming Class.

Honestly, I'm not a game maker, I'm a simulation programmer.

I just wanna get the project done in time for my class.

Once this class is over, I'll actually have time to sit down and play around with things.

BTW You guys have the wrong idea to what I want...

I want the camera to turn in the direction that the mouse is moving, when the mouse button is pressed.

...Triple post?

I am very confused, at first you asked for this:
Quote: "Like rotate around the position of the mouse, so I'm always looking at the mouse/center."


Then when we answer, you say thats wrong and you want this:
Quote: "I want the camera to turn in the direction that the mouse is moving, when the mouse button is pressed."


The second one is on the forum already a few times at that. Check out the search function, its leet.
