is this a bug? <http://i.imgur.com/Vz4LWQE.png>

in Entity,   Entity &lt; Particle &lt; HitParticle

but seems like the issue is velX, wich is only defined in HitParticle

i first converted from java to kotlin using IDE, but even rewritting from hand cause issue, i tried to invalid cache but still same issue

Is there a `var velX` defined in `Particle` or `Entity`?

if i put var in constructor, the variable is defined in that same class right ?

i removed out/ folder and did again invalide cache we'll see if that fix it

Yes, I see the `val velX` in `HitParticle`. But is there a `var velX` in any of its superclasses?

Try making the smallest example you can that reproduces the issue. It might be easier to debug.
