| Summary | 0004838: shields are shaky instead of being drawn precisely centered on fast moving units, sometimes | ||||
| Description | My game has aircraft and land units with small bubble shields around them when I move them around sometimes there are bursts of frames where the shield rendering is shaky, like it's having trouble keeping up with the units' position instead of being perfectly centered on every frame the problem occurs in 96.0 and 98.0+ but it works fine in 94.1 | ||||
| Steps To Reproduce | you can use the old version of metal factions which is still public : 0.7 http://springfiles.com/spring/games/metal-factions start a game - disable luarules (to stop gadget errors) on spring 98+ - /give 5 sphere_twilight (shielded heavy fighter aircraft) - order them to move around and watch them for a minute or two | ||||
| Additional Information | note that this is unrelated to other visible aircraft shaking behavior. that's another issue. | ||||

I believe this isn't an issue of the shields, but an issue of the unit having brakerate=9; maxvelocity=9; |
|
|
don't think so. It also happens on my testbed version where those fighters have 0.09 brakerate. (btw on that version I have code that divides aircraft's brakerate by 5 if > 0.5 on unitdefs_post) |
|
|
anyway, I don't see the shields shaking specifically, and I couldn't reproduce with ZK shielded units. |
|
|
This is odd. The problem doesn't show on spring 99.0: there are still occasional bursts of stuttery movement sometimes (without drop in framerate), but the shields now seem perfectly centered with the unit. I'm using vsync locked at 60 fps btw Tested again and I confirm the problem did happen on 98.0.1-727-g986777d. It may have been fixed somehow. |

was already fixed when you opened the ticket https://github.com/spring/spring/commit/2ea58560b4dc8330dacba799278c44e47bd022c0 |
