Bus on water bug (win32)

[weeble888]

after removing a bridge I found that in the water where the bridge had spaned was a bus which was just about to cross from the North East end. I installed the latest nightly (03 May) and the same problem reoccurs. attached is a picture of the offending bus

Any chance that you can post your savegame and openttd.cfg please.

Which bus? To me it looks like all busses are on the bridge.
Please post savegame + openttd.cfg and exact instructions which bridge and when to destroy. Best would be a savegame in paused mode and you saying destroy bridge1 and the bus goes swimming.

The bus which is in the upper part of the lake behind the office block I've attached an autosaved game and the cfg file

OK that bus does the same thing as the bug i recognized while coding the bridge upgrade patch. I never reported that . The bridge can be removed while a bus is on it. Dunno now if you need to demolish the bridge tile on which the bus is or another. But if i remember correct it has to be not a ramp, the bus was on the bridge and not on the ramp (maybe regardless). The bridge was over water while the ramps are on slopes.

OK after some tests, it apears to trains and road vehicles. The vehicle has to be complete on the bridge and both ramps need to be empty. The bridge must go over water. The tile selected to demolish does not matter

So enough for today time to sleep

here is a picture of the reproduced bug:

It happens on any tile type. This code is wrong:

Code: Select all

	/* Bridges on slopes might have their Z-value offset..correct this */
	v = FindVehicleBetween(
		tile    + delta,
		endtile - delta,
		TilePixelHeight(tile) + TILE_HEIGHT + GetCorrectTileHeight(tile)
	);

It works for bridges with sloped ramps, but not for flat ramps...
