[1.187] small airvent reads planetary atmosphere wrong.

Large airvent reads 0.8911.

Small air vent read 7.1288.

This is 712.88% vs 89.11%

Problem appears to be at SpaceEngineers.Game.Entities.Blocks.MyAirVent.GetOxygenLevel()

If EnvironmentOxygen is 0.8911, and room is not pressurized.

LargeGrid returns max of (0.8911/(2.5x2.5x2.5) or 0.8911

returning 0.8911

SmallGrid returns max of (0.8911/0.5x0.5x0.5) or 0.8911

returning 7.1288

Going deeper into oyxgenBlock.OxygenLevel=> OxygenAmount

OxygenAmount has a float value = (float)(this.Room.IsPressurized ? (this.Room.OxygenAmount / (double)this.Room.blockCount) : ((double)this.Room.EnvironmentOxygen));

So going back to MyAirVent.GetOxygenLevel

If the room is not pressurized then OxygenAmount will be EnvironmentOxygen, but GetOxygenLevel does a check of IsPressurized before the return.

So large grid returns environmentOxygen but small grid returns environmentOxygen/0.125

Suggested fix change GetOxygenLevel from

public float GetOxygenLevel()

{

if (base.IsWorking)

{

MyOxygenBlock oxygenBlock = this.GetOxygenBlock();

if (oxygenBlock.Room != null)

{

float num = oxygenBlock.OxygenLevel(base.CubeGrid.GridSize);

if (oxygenBlock.Room.IsPressurized)

{

return num;

}

return Math.Max(num, oxygenBlock.Room.EnvironmentOxygen);

}

}

return 0f;

}

to

public float GetOxygenLevel()

{

if (base.IsWorking)

{

MyOxygenBlock oxygenBlock = this.GetOxygenBlock();

if (oxygenBlock.Room != null)

{

if (oxygenBlock.Room.IsPressurized)

{

return oxygenBlock.OxygenLevel(base.CubeGrid.GridSize);

}

return oxygenBlock.Room.EnvironmentOxygen;

}

}

return 0f;

}
