How advanced are your math skills?

[wonder]

I never thought that creating videogames would require me so much to improve my math skills. I still struggle with a lot of concepts, since I was never a math wizzard. At the same time, having to remember what I've learned in high-school brings back a lot of good memories from those times.

If only I enjoyed math and physics back then as I do enjoy them now, life would have been so much different.

I'm good at math but in my schooldays I asked myself "what is it good for? I will never use that stuff in my whole life". Now I know. I started to play arround with libgdx. Now I know what "this stuff" is good for

LibGDX indeed!! Hello trigonometry, hello collision detection, hello physics!!

By the way... How did you create your sprites (Ninjas)? Tool? Little sister with excellent graphic skills?

The sprites for Project Ryu? I stole from Capcom. The sprites I'm using are from Street Fighter III - 3rd Strike.
By the way, I have excellent graphics skills! I do not, however, have any drawing skills, nor does my sis...

Ouch. Another app which is in danger to be banned from the Playstore

It's not on Google Play.

"Under the influence of Capcom, SNK and Team Ninja, I decided to create this small tech-demo. There's a lot of copyright infringement here, so this app isn't going anywhere near Google Play."

My Maths it OK, but when it get's down to vectors etc., the internet is my friend It's a long time since my maths at school. I did a course in Astro physics, but that was mainly Sin and Cos. Someone once told me it's not what you know, it's knowing where to find it! And I live by that to this day. And with the internet these days, it pretty easy.

The trick is , knowing what you're looking for.

I can draw a circle.

Since starting to write my own games, I've found trigonometry to be the most useful math skill. If you want to do anything more than 8 directional movement, you need trig. Other than that, just simple maths for adding things like gravity and smooth movement by using fractional speed changes is all I've really needed.

 

[sorex]

didn't know there's more than 8-directional for 2D games ?

 

[WAZUMBi]

For the most part only a good knowledge of algebra and a basic understanding of geometry and trig is all I've ever needed.
But then again I only develop basic 2d games and apps.

Sure for platformers or tile based games. If your tiles are anything other than square such as hexagons...

 

[andymc]

I meant more than 8 directional movement for players, an overhead tank game may have 360 degree movement. The old game Cannon Fodder on the Amiga had full 360 degree movement for the soldiers and weapons fire.

 

[sorex]

I know, but 8 directional means 8 directions as left/right/up/down/ul/ur/dl/dr so the diagonal ones are not limited to 45° angles only.

look at many 80s games, once you fall at certain velocity you have certain angled scrolling based on the x & y velocities.

@sorex
I think you are mixing between directions and dimensions.
