@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!
I am d.y.i.n.g on the vine. Trying to use tangram-sandbox with react. I can use tangram with react. But when I try to use gotham or tron as the scene file.... nothing. No errors, nothing in my console, just blank screen. Pleaseeeee tell me someone out there is willing to help? Thank you

Also @patriciogonzalezvivo congrats on @runwayml!
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.

Hi,
I'm trying to draw polyline but nothing is shown in the map
here is sample of code
val polyline = mController!!.addMarker()
polyline.setPolyline(Polyline(list, HashMap()))
polyline.setStylingFromString("{ style: 'lines', color: '#009ecc', width: 28px, order: 1200 }")
polyline.isVisible = true
any idea wha's the problem ?

hello guys, I'm struggling with tangram-es, I'm getting this "WARNING urlClient.cpp:375: Failed with error for url: The requested URL returned error: 403" while I think I've correctly set my NEXTZEN_API_KEY and i use the default scene.yaml ... any help ? thanks Guys

my cmd is "./tangram -f ../../scenes/scene.yaml", it is able to find the yaml file but ...
the build was ok
it generated the tangram in build/linux
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!
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

I think you would need to pass a new uniform corresponding to your animation parameter
Hello all, I have a problem. I want to overzoom a vectorial map that have data available only until zoom 8 on a mobile Device that run a UBUNTU base Tangram ES SW on it. All ok until zoom 10 but if I want to overzoom more, the icons and texts have rendering issues..like here:

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
So that they can be used with tangram-es default styles (e.g. the scene.yaml in the repo of tangram-es)
@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?
Exist possibility to upload a grid map? I have 5x5 degrees coverage for every map and I want to upload several in the same scene.yaml. The maps has same layers and same data type. Only covered surface is different. I can view concomitant several maps of the same type?
