Hi,
This forum is for Obi assets. For questions related to other assets, please use the appropriate support channel (for FluXY, emailing to fluxy(at)virtualmethodstudio.com).
This game definitely uses an eulerian, texture-based fluid simulation, so yes FluXY would be the correct choice.
Using torque / target scaling is a quite convoluted way to do this, increasing pressure (alpha channel of the velocity texture) would be a simpler, more effective way.
As in any fluid simulation, fluid spreads from high-pressure areas to low-pressure ones. So increasing pressure on a point will make fluid flow outwards from it.
Note that for accurate pressure-based effects you need your solver be using the Iterative pressure mode, instead of the Separable one.
Make sure all dissipation values in your container are set to zero, then use a low-precision storage asset for your solver (this will prevent density from dissipating over time). Check the "Fog" sample scene for an example.
You can initialize the container's density values of the container using its "Clear color" property, under the "Surface" foldout. This will fill the entire container with an opaque color.
kind regards,

Second question is, is there a better/easy way to achieve it?

Is there a better way to spread it and eventually make it look completely filled with no motion?
