Unity Animation Design Help

So I am working on a 2d game in Unity where the player can climb walls. The climbing is more like what real life climbing would be, not the generic 2d climbing we usually see where the player just sticks to a wall and walks up it. My current design of what this climbing system would be is to have a mesh that represents a wall, and have some kind of system that allows the player to climb the wall by pressing buttons and moving to the next "point" on the wall mesh. 

 

I believe this would allow the player to actually climb along the wall, but I am thinking about how the animation would work, and I am having design issues. I am curious as to some common ways to design animations so that they look "correct" when a player is moving towards a point with his arms and legs. The players body would need to rotate properly as he is climbing the wall so that he appears to be touching the wall, his arms and legs would have to be in the correct positions, etc. 

 

I know my question is pretty vague, but if I have conveyed enough information, and you have any ideas that came to you as you read this, I would appreciate some general guidance or wisdom on this. Thank you very much!

the common way is to apply classic techniques of character animation using forward kinematics or inverse kinematics.

there are a number of books and courses, and a few online tutorials on the subject.

 

its an artistic skill, just like painting or 3d modeling / sculpture.

A climbing game would likely be using a Forward kinematic solution using inverse kinematics to reach and position the hands and feet.

 

Inverse kinematics solves a character's pose by positioning the terminal joints and then solving the system back towards root joints using some constraints. Generally inverse kinematics by themselves looks poor as it's missing all of the nuanced movement you get from motion captured data (forward kinematics). Forward kinematic solutions by themselves don't work since they have no way to adjust the hands and feet to properly place them where they need to go.

 

Blending the two generally produces much better results (keep all the nicely captured realistic movement from motion capture while still adjusting the hands and feet to be positioned properly).

      Hi , I was considering this start up http://adshir.com/, for investment and i would like a little bit of feedback on what the developers community think about the technology.
      So far what they have is a demo that runs in real time on a Tablet at over 60FPS, it runs locally on the  integrated GPU of the i7 . They have a 20 000 triangles  dinosaur that looks impressive,  better than anything i saw on a mobile device, with reflections and shadows looking very close to what they would look in the real world. They achieved this thanks to a  new algorithm of a rendering technique called Path tracing/Ray tracing, that  is very demanding and so far it is done mostly for static images.
      From what i checked around there is no real option for real time ray tracing (60 FPS on consumer devices). There was imagination technologies that were supposed to release a chip that supports real time ray tracing, but i did not found they had a product in the market or even if the technology is finished as their last demo  i found was with a PC.  The other one is OTOY with their brigade engine that is still not released and if i understand well is more a cloud solution than in hardware solution .
      Would there  be a sizable  interest in the developers community in having such a product as a plug-in for existing game engines?  How important  is Ray tracing to the  future of high end real time graphics?

      Good day,

      I just wanted to share our casual game that is available for android.

      Description: Fight your way from the ravenous plant monster for survival through flips. The rules are simple, drag and release your phone screen. Improve your skills and show it to your friends with the games quirky ranks. Select an array of characters using the orb you acquire throughout the game.

      Hello fellow devs!
      Once again I started working on an 2D adventure game and right now I'm doing the character-movement/animation. I'm not a big math guy and I was happy about my solution, but soon I realized that it's flawed.
      My player has 5 walking-animations, mirrored for the left side: up, upright, right, downright, down. With the atan2 function I get the angle between player and destination. To get an index from 0 to 4, I divide PI by 5 and see how many times it goes into the player-destination angle.

      In Pseudo-Code:
      angle = atan2(destination.x - player.x, destination.y - player.y) //swapped y and x to get mirrored angle around the y axis
      index = (int) (angle / (PI / 5));
      PlayAnimation(index); //0 = up, 1 = up_right, 2 = right, 3 = down_right, 4 = down

      Besides the fact that when angle is equal to PI it produces an index of 5, this works like a charm. Or at least I thought so at first. When I tested it, I realized that the up and down animation is playing more often than the others, which is pretty logical, since they have double the angle.

      What I'm trying to achieve is something like this, but with equal angles, so that up and down has the same range as all other directions.

      I can't get my head around it. Any suggestions? Is the whole approach doomed?

      Thank you in advance for any input!

      Hello,
      without going into any details I am looking for any articles or blogs or advice about city building and RTS games in general. I tried to search for these on my own, but would like to see your input also. I want to make a very simple version of a game like Banished or Kingdoms and Castles,  where I would be able to place like two types of buildings, make farms and cut trees for resources while controlling a single worker. I have some problem understanding how these games works in the back-end: how various data can be stored about the map and objects, how grids works, implementing work system (like a little cube (human) walks to a tree and cuts it) and so on. I am also pretty confident in my programming capabilities for such a game. Sorry if I make any mistakes, English is not my native language.
      Thank you in advance.
