Change Details

Terrain cellSize is an important parameter for various terrain-related calculations, because it represents the "accuracy" of the terrain. [[ https://pmc.editing.wiki/doku.php?id=arma3:terrain:grid-cell-size | Sample list for all vanilla A3 terrains]] It's weird that there's no command or config value to get the terrain cellSize. sample command: ``` getTerrainCellSize ``` It doesn't require any parameters. Similar to WorldSize. or a config value: ``` cellSize=x; ```

Currently there is a command in diag exe `diag_getTerrainGrid`. But that command is just a getter of terrain cell size and it's perfectly safe and useful for stable branch as well. I previously asked for that command but sadly another ticket requesting the command to be added to diag exe was accepted.... :( So instead, I'm gonna ask a new command: `getTerrainInfo`, which is more general. This command will return an array of 2 values: The terrain cell size and its heightmap resolution. `[cellSize, heightMapResolution]` This command can be further expanded in the future to return more useful terrain info. (I can't currently think of anything more) The cell size is an important attribute of the terrain. For example, you can know where the terrain "slope" is gonna change (which is the next adjacent cell triangle) compared to the current pos. This feature can be useful for scripts that find "empty and flat positions", as currently there's no good approach to do this (if you pick small "step", the algorithm is slow; if you pick a large one, it's inaccurate...) There are many other applications as well.
