    @matteblair I'm on it! I already have two changes, so I'll definitely take note of what I have. I'll keep poking in the chat when I run into stuff I don't understand

    ok first question that doesnt have a google result: I finally got the manhattan map to load but i cant zoom out or move at all - whats the best place I should try and debug here?

    @fernancode It looks like the code has event handlers for keyboard inputs, so I would start by trying to use a keyboard if you aren't already. Beyond that, you'll probably want to use general C++ breakpoint debugging techniques to see where things are not happening as expected. The repo has probably only been tested on a Raspberry Pi from 6 years ago. @patriciogonzalezvivo is the original author of the code, but not sure how well he'd remember the code at this point!

    Are there any good examples for how to draw a circle with a gradient (semi transparent) background in tangram? Would I use a shader for this sort of thing?

    is it possible to draw a line without reloading the scene, and if so is there an example somewhere? i got something like it to work by dynamically making an update to a layer in the scene to filter some line segments and style them differently, but it causes the entire screen to flash

    I'm using Tangram-ES for iOS to implement a map that is constrained to a rectangular area. Is there a built-in way to do that? I didn't find one in docs but it seems it should be possible.

    Can anybody comment on the state of the RPI platform?

    It doesn't compile at the moment because of the use of the obsolete Url::resolved() method.

    Can anyone report which of the many Pi and O/S versions were used to develop and test this code?

    In a port to a Mesa software OpenGL stack, I'm seeing mirror-image output running the tangram-es test app.

    Does anybody know what might cause this?'

    Is there a way to position the camera/projection for a Tangram map in a similar way to navigation apps? E.g. https://raw.githubusercontent.com/mapbox/mapbox-navigation-ios/main/docs/img/navigation.png

    I'm still working through this library, but I'm sort of feeling stuck. I need to be able to animate a circle growing a certain velocity from a point. It seems there isn't a circle polygon, but maybe drawing a circle could work, but then how would I animate it? The other option seems to be a shader, but I'm not certain how I would place a shader on the map and have it render at a specific point? I've been searching for hours. Please, if anyone has any suggestions or examples, that would be great!

    @thertzelle
    Like there is a shader circle example: https://github.com/tangrams/blocks/blob/gh-pages/shapes/circle.yaml
    But then how do I place that on my map with Tangram ES?
    Then I assume I would have to figure out how to use shader code to animate the circle

    @bdon_gitlab
    @thertzelle what about rendering the circle using a Leaflet layer on top of tangram instead of via webGL? Then you should be able to use CSS transitions. oops, I didn't read to the end - realizing you're using ES, not web
    I think you would need to pass a new uniform corresponding to your animation parameter

    Do you know which can be the cause? Is possible my mobile Device OS have some limitations or bad configs? Or my scene.yaml is not ok?
    On PC viewer and Tangram Web all ok with my scene and map

    Hiya!
    How can i "ask" tangram to keep the original angle of a sprite?

    For example i have a fix angle 45, want to see this sprite always in this exact angle, regardless what the current view is.
    So basically i don't want it to be rotated at all.

    Cheers!

    Is there some documentation on how to make mvt from geofabrik downloads?
    So that they can be used with tangram-es default styles (e.g. the scene.yaml in the repo of tangram-es)
    Brandon Liu
    @bdon_gitlab
    @mathisloge take a look at https://github.com/systemed/tilemaker ; you could customize the tile creation via Lua to match the tangram/mapzen cartography

    Did any one obsered that loading a Vectorial layer for example on low zoom (for example zoon 3-5) and set max_zoom: 5 (max zoom to request tiles) and max_display_zoom:18 to overzoom last available tiles set untill zoom 18...there is a huge memmory leak (I can easly reach RAM limit even on a PC with 4 GB RAM only by zooming IN and zooming out more times). Each time the RAM increase until limit is reached. It seems a n issue in Tangram rendering overzoom textures
    I used latest version available on GIT to obtain this issue(is also obtainable on older versions). Is there a special settings I must consider or this is a known issue?
