Allow Spy to Disguise as Certain Units Without Crash

[WilliamWsyHK]

I tried to disguised the Spy as Rocketeers, but of course it would fail because IIRC in the original game it just pretend to be walk on the ground, but it gives exception instead.

Exception of type `System.InvalidOperationException`: Unit `spy` does not have a sequence named `fly`
    at OpenRA.Graphics.SequenceProvider.GetSequence(String unitName, String sequenceName)
    at OpenRA.Graphics.Animation.PlaySequence(String sequenceName)
    at OpenRA.Graphics.Animation.PlayRepeating(String sequenceName)
    at OpenRA.Mods.Common.Traits.Render.WithInfantryBody.Tick(Actor self)
    at OpenRA.WorldUtils.DoTimed[T](IEnumerable`1 e, Action`1 a, String text)
    at OpenRA.World.Tick()

    at OpenRA.Game.Loop()
    at OpenRA.Game.Run()
    at OpenRA.Game.InitializeAndRun(String[] args)
    at OpenRA.Program.Main(String[] args)

We should be allowed for spy to disguise as certain units, without any crashes.
(Disguise ready)

Confirming, I just got a similar

OpenRA/OpenRA#17742 might have already fixed that.

Any workarounds for this, we just had a crash middle of a game.

On a tangential note, how does one get started with development (on Linux)? I didn't find too much information in the book and contribution guide.

[Mailaender]

There is a patch at #786 which has not yet been integrated.

[Mailaender]

The https://github.com/OpenRA/ra2/wiki should get you started. Ignore the book as it is incomplete and unmaintained.

[testman42]

just got

Exception of type `System.InvalidOperationException`: Unit `spy` does not have a sequence named `idle-air`
