In Topic: How much Maths/Physics do I have to know?

You already know enough. Have a firm grasp of vectors and keep making games.
If you eventually need something more it will be specific to your project, and you can learn it then.

In Topic: Hololens kit $3,000?

Honest question:


If valve's vive is already tracking head's rotation&translation, and has a camera on the outside... what stops this piece of hardware from supporting AR very easily?

I mean, if I know where your head is and what are you looking at...  what stops me from showing you the camera input + something added to it?

In Topic: Best way to check collisions with multiple objects?

28 January 2016 - 10:57 AM

Multiple questions here, albeit related. I would suggest to keep your collision checking independent from rendering - who says entities outside screen don't need collisions? They want some collisions as well!


This is true. Things outside the screen may collide too (ie: a bullet against a wall).



There are several ways/algorithms to not check your character against ALL things in the world. The phrase you need to google is broad phase collision detection, and its purpose is to discard (very fast) the objects that are so far apart that it's impossible that they are colliding.


One simple way to do that is with a grid. You divide your world in squares and every object belongs to a square, you find the square by: (position.x / widht_of_square, position.y / height_of_square). That way when you have to check for collision you only check against the objects on the same square (and probably neighbors too).


Hope that helps to get you started.

More data.


If I open the downloaded file with chrome or firefox, (3) is shown.

If I use the other applications, I see (4).


Edit: Yeah, those two browsers actually modify the image to what they think it should look like. (4) is the correct cmyk.

In Topic: Cocos2d-x...... :'(

I enjoyed SDL2

I really like C++ so far

I'm not in a hurry


Good! Then stick with it, you are already having fun and on your path to make games.



my goal in the longer run is to try making games for iOS and android, I thought I should find a tool that would suit those needs.


If you learn C++ and SDL2, Cocos2d-x will be easy when the time comes.


You will be able to adapt to anything they throw at you. So don't worry about your future plans, you will be changing laguages/tools all your life. Learn to program and to make games... the tools will come and go.


Good luck.
