here's how it goes. We are using circle packing algorithm to pack circles of different dimensions and colour at the centre of the screen. the circle dimensions and color are stored in an array list.

we did a mouse over effect in that whenever the mouse hovers over a particular circle, the particular circle's dimension will be enlarged (and that's the c.radius with 0.02) and the colour changed. this is to allow user to see the content (keyword) of the circle.

the above went ok.

Our problem starts to come when we try to also alter the surrounding circles dimensions that touches the moused over circle.

we are able to retrieve the surrounding circles dimensions basically a radius value. but we have difficulty altering it during the next draw cycle. the surrounding circles still took on the old dimensions. In other words to we have difficulty getting processing to accept the temp new radius for all circles surrounding the moused over circle.

Any advise how you would do this?
