Tech Log #029: Drag & drop works

by | Dec 7, 2020 | News, Tech Logs

The drag & drop functionality now works! Check out the gif. By a count, about 8 methods were tried before reaching one that worked. Thought about the problem a bit differently, broke it down into tiny steps, and with a bit of tinkering, it works.
 
 
Dragging the square to the marker makes the marker change to green. Moving the marker to the square also makes it change to green.
 
One of the methods that was close to working but not quite was aframe-mouse-dragndrop. I made some changes, which are viewable in this git diff. Main change was line 76: .add(this.direction.clone().multiplyScalar((this.dist + this.range) * ((-1*zPos)-1) ));. The other big changes were thanks to bknill for the initial parented entities fix.
 
 
The next step is to clean up the code that works, and integrate it with the ‘full’ codebase. After that, continue with the device hardware. There are plenty of ways to make it even better, but for now the aim is to make a complete working prototype.

Tech Log #028: Stuck on Aframe drag & drop

by | Dec 4, 2020 | News, Tech Logs

There is a key piece of functionality for the user that is missing from the current AR mode of Terrapulse. That is, the user has to be able to drag and drop something onto the marker – and have an effect, like an animation or something. Eventually this would be used to display more information. Anyway, turns out that implementing this feature is not as straightforward. Spent most of the time searching for Aframe modules that would enable this. There’s one that kind of works, but needs some improvements. This will have to be looked at again tomorrow. Next step is to revisit this and try it again.
