Thread: Image problem

I have a little program running and i can add 'sprites' onto the program and they can move

However, i am having trouble finding help for rotating a stationary image.

Code:

GameFramework Game(0);  

CreateNewScreenItem Sprite1(0,-3,8 ,1); // When a new characteris added

I used this to add the image, and it just sits there

Just wonderng if anyone can help me from this, say i link to a tutorial or something?
If you need more code, just ask

Whatever that is, it's not straight C. Is this from a certain game library, or C# perhaps? Need more info.

Oh sorry, its C++, i must have posted in the wrong place

There is no way we can tell you how to rotate a sprite with the information you have given. The sprite class should have a rotate function. If it doesn't and it is raster-based then rotating the image is going to be extremely difficult. If it is a Direct3D or OGL based sprite then you would need to rotate the quad via transformations.

Thanks guys

Well i am doing a carHUD and want the speed-o-meter to move starting from the left -90 degrees and rotating a full 180 so its now 90 angle.

Nothing wih acceration right now, just rotate at a content speed.

Just looking for a tutorial or some help on here would be nice

Will post code abit later when i get home.

This is the code i currently have:

I will be adding a SPEEDOMETER item
and NEEDLE item

I need the needle to beable to rotate 180degrees to show the speed of the car

Code:

GameFramework AdventureGame(0); //You must create a new instance of the game for every new game.
CreateNewScreenItem RABBIT(0,-1 ,8 ,1); //When a new character or baddie is needed.
CreateNewScreenItem SNAIL (0,1,23,0);
CreateNewScreenItem GEARBOX (-1,-1,2,0);
CreateNewScreenItem GEARBOX1 (20,-1,2,0);
CreateNewScreenItem GEARBOX2 (20,-1,2,0);
CreateNewScreenItem GEARBOX3 (20,-1,2,0);
CreateNewScreenItem GEARBOX4 (20,-1,2,0);
CreateNewScreenItem GEARBOX5 (20,-1,2,0);
CreateNewScreenItem GEARBOX6 (20,-1,2,0);

		return true;
	else 
		return false;
