There are various event handlers you can use with HDA's (like onCreated, onInputChanged etc.) but I can't seem to find one that can be used as a callback for when the output connection of the HDA changes.. Basically i'm trying to create a custom version of the gas disturbance, part of which has the option to visualise the block size of the disturbance (just with coloured points on a grid). So I was thinking I would use an event handler on the HDA to know when it was connected and then in python traverse down the children to find the solver then traverse back up to find the smoke object so I can get the size and center to position the grid correctly. Is this possible? Is this a stupid idea?
