Hi people,
a question i’m a beginner on math and physic
do you know an easy approach good book or resource on basic math for unity?

How to use physic engine properly?
How can i use physic with keyframe animation ?

Thanks have a nice day.

This is a great intro to vector math

Thanks meltdown!

I think the level of physics and math that you need to know strongly depends on what you want to do. For some applications you need very basic knowledge, for some you need very high levels of mathemathics and physics. I believe that what you want to do is physics related, studying an engineering 1st year level pyhsics book would be very beneficial (not the electrical part but mechanial part) there are many many such books. Also analytic geometry is helpful.

Thanks tig,
ok so if i want to know what happens with ageia physx lib integrated in unity what kind of phisic part i have to study?
Thanks for reply , i’m not an expert.

Start with the help files, there’s a lot of examples in there. Google for unity + physics and watch youtube videos. It is better to learn by doing, ie making a ball, giving it a rigid body component then giving it a collider component.

Do the same for a cube below the ball, make the cube kinematic and turn off gravity for it. Turn on gravity for balls. These are all options you see once you add rigid body + collider components via the menu to them.

Experiment. Then if you need to do it in code it is the same, with easy commands that match the graphical ui approach.

I meant all the parts excluding electrical ones :smile:

Hi thanks for your reply ,
i’ve ordered 2 books on phisic for game programmers (one is very good because explain for very beginners like me)
i hope they help me .
After study the books i return to see buzz lessons on physic hoping to learning the concept better.
My problem is how to use character animation with physic simulation.
Example: if there is an explosion near the hero →
hero.animation(something precalculated) OR
hero.calculate(new physical based animation which i don’t know , maybe like a procedural animation calculated in real time)
Thanks bye.
