Scenario Editor river placement flood fill tool

[jimbob]

The Ctrl click is a big improvement for placing rivers, however it is still tedious when drawing out a river even if one tile is invalid no rivers are placed and an error message is shown, instead it should have the valid tiles to have rivers placed on them. Much like the level land tool will still try and level as much of the selection as can be edited, despite there being buildings or other objects. Even better would be a flood fill and all connected tiles on the same level be made river so it would be easier to fill lake basins from heightmaps.

If you create the elevation map so that wider rivers and lakes are also at sea level, you won't have a problem. However, as soon as you want to create lakes and rivers above sea level, you will of course have to draw them in manually.

the issue with this is that it butchers the topography by making it several hundred meters below all the surrounding tiles. this game can't go from 650 meters to 0 in one height difference, and even if it did, it would be a giant canyon in the ground. something like the alps, with all its lakes at very high altitudes, wouldn't work at all. tall mountains are already hard to render accurately by the fact that their peaks reach very high altitudes in a very short distance, shorter than openttd can represent a height difference in. having a lake drop the level from 560 meters down to 0 exacerbates this further. on small scale maps the issue of manually placing lakes is fine, but imaging an 8kx8k or god forbid a 16k by 16k where you have to manually do the great lakes.
