Question

just a quick question.

I want to make a 3d game in OpenGL on a Mac but I’m not sure how to make a Vec3f class in objective c.

I would really like to be able to set the class like,

    Vec3f *point = {1,2,3};

but still be able to treat it like a class.

The only I things can think of is use a typedef struct or use regular objc setters like

    -(void)setX:(int)X{ x = X; }

I don’t know. Any Suggestions.

EDIT: Just to be clear I want to be able to set the class as if it was an array. I don’t need to know how to make the class, I just want to be able to know how to set the class with curly braces. Thank you.

You can’t do this in Obj-C. It doesn’t provide any mechanism to do alternant initialization like that. Your best bet is to do something like this…

+ (id)generateVector:(float[3])vec;
{
  //set internal structure
}

[Vec3f generateVector:{1,2,3}];
