The purpose of this demo is to show how to achieve smooth motion while moving objects or the camera, in both simple translation mode and a "flying" mode.
It can also serve as a playground for testing ideas before committing them to your game code.
I use non-standard keys (ie., no wasd) so that it is obvious what axis one is manipulating.
For this reason the first run through, at least, should be done in accompaniment with the instructions.txt file.
G3N engine is a 3D game engine written in Go.
Also see G3N for related links.
g3nmovedemo only depends on the G3N game engine and so has the same dependencies as the engine. See those dependencies at the link above.
In order to run, build, and or install you will need Go installed on your system. Search for "golang download**, the process is quite simple.
Either clone/fork this repo to a folder of your choice, or, from the code button on this page, select to download a zip file, unzip that in a the folder of your choice.
From that folder use either "go run ." to run a temporary copy, or "go build ." to build an executable in that folder.
When you do either of these Go will download the g3n engine and anything it depends on, if you don't already have it on your system.
The first run or build will may take a little longer while if things must be downloaded.
Be sure to have a copy of the instructions.txt file open so you can walk through the available commands and features.
Gopher model was derived from the same model used in gokoban, which gives the following link:
Gopher 3D model from: https://github.com/StickmanVentures/go-gopher-model
For the purposes of this demo the model was changed by me (in Blender) to get the origins to geometry, parented everything to body, changed the orientation to be correct (face looking down negative Y axis), and added an animation.
