| Summary | 0001756: Hole in the world when heightmap is set to NaN using Lua | ||||||||
| Description | I doubt this bug would ever occur but I heard that Spring devs want to hear about any crash that lua can cause. Sometimes bugs in my terraform gadget cause the manipulated parts of the map to disappear. I assume that something has been divided by zero. Strangely Spring does not crash at that point. This crash occurred when a unit walked into the hole, at this stage the water plane (water 0) was flashing on and off. | ||||||||
| Additional Information | Spring 0.80.5.2 (0.80.5.2-5-gcb5d5b5{0.80.5-branch}-cmake-mingw32) has crashed.

Example how to reproduce? Similar construct like 0001470. Bad parameters for LevelHeightMap didn't crash Spring directly, but when the map was rendered. |

Create a ramp at least 2 segments long and 1 segement wide using the modified terraform gadget. The only modification is line 1507, in the working gadget the line is 1506. It's got a lot of knock on effects though as the modification screws up the indexing on a table used to check intercepts. |

Could reproduce this after some time. It's really void area: There is no tooltip for the area, nor is any command allowed (move etc.). Units will block at the edge. I used air constructors for terraforming, those who were in the void area when it appeared where frozen, didn't move anymore. They could only move out by "bumping" with other planes. If I move the camera center (cross) into the void area the screen gets white. Flicker appeared later. Not just water, but also the land flickers. It flickers only when the game is running - no flicker when paused. Tested with default settings + lups disabled. I'll try to create a smaller test case. |

Reproduced by: local a = 0 local b = 0/a -- nan Spring.SetHeightMapFunc( function() for x = 1, 100 do for y = 1, 100 do Spring.SetHeightMap(x,y,b) end end end ) Seems all height map function have this problem. |

Probably many more than just those related to heightmap manipulation; Spring can not be expected to sanitize every possible Lua-provided argument. |
