In Topic: Finding right vector to resolve collision

Yesterday, 04:19 PM

You could find out what edges are internal to the geometry and mark those so they are ignored in collision.

 

Another thing I would recommend anyway would be to make your character collision shape a sphere or a pill shaped. Having rounded edges will help your character slide over edges. This will help prevent the player from getting stuck on small bumps.


In Topic: Best Way to Learn 3D Computer Graphics? Help!

16 November 2014 - 08:55 PM

Half my gut tells me to jump into Direct3D and keep plowing away at it while learning the math that is only necessary. 

 

This is how I learned 3D graphics. If you are excited about what you are doing you will be more focused and do it more often so you will learn faster.


In Topic: type cast float to int or other alternative?

16 November 2014 - 08:50 PM

This has me a bit overwhelmed...... What if I want my objects to run on their own independent frame rates?

 

Each sprite can have a different value for frequency that determines its own framerate


In Topic: Anyone interested in teaming up?

Don't mean to be rude, but before teaching someone without experience how to program you should be able to at least finish that Pong remake. Maybe you're really good at everything but AI, I don't know, but not being able to finish what is usually considered a "first game" for learning purposes doesn't look too promising.

 

Aside from that, if you want to create a team of any size you should go to the classified section. You'll probably become friend with your team even if you know them through the classified section if you enjoy working together or won't become friends if you hate the process. I'm not sure how making a team with people using the classified section is different.

 

I don't see any problem with him wanting to share what knowledge he has so far. Actually, I think it is a good idea to not have too much of a gap when teaching somebody. I sometimes find it very hard to teach game programming to absolute beginners. I forget sometimes that things that comes naturally to me now due to years of experience may not be so obvious to them.


In Topic: Bitblit from buffer to screen

15 November 2014 - 06:13 PM

To get data from a bitmap to the screen, copy the data into a texture using glTexImage2D. Then draw that texture to the screen on a quad

 

To get the data from the buffer you can use glReadPixels
