Is there videos that can visually help me understand line of sight and massive movement I have the rule books but I would like to see it

There’s a a lot of good pictures in the end of RRG demonstrating LOS. Basically you have to be able to draw 2 different straight lines from one corner of your character to 2 corners of the target figure, whilst the lines don’t overlap. For massive figures you pick up the figure and move it like it’s a small figure (one space at the time even though it takes up 6 spaces) up to its speed.

But also don't forget that all large figures (including the massive figures) can only move orthogonally, not diagonally.

Not just any two corners. Line of sight must be drawn to two adjacent corners of the target space. (One of the spaces the Large figure occupies.) Note that line of sight can be drawn through the attacker and the target, and figures do not block line of sight to figures with the Massive keyword. (not even other Massive figures)

Also, the required accuracy is determined separately from line of sight, and it is not the distance to the target space, but the distance between the figures (see Counting Spaces).

All figures move 1 space at a time. Large figures cannot move diagonally.

Massive figures cannot enter spaces with other massive figures.

(Yes, see the appendix from the RRG.)

After playing for a few years I'm still learning new rules . Are you saying that if one was to target one of the back spaces of a large figure (say to trigger blast on figures adjacent to that space) that the accuracy is still determined by the closest space that the target figure occupies, and not necessarily the distance to the target space?

Back in the day we took it granted that target space determines the required accuracy. However, there is no such requirement set in Large Figures.

If a Large figure attacks, LoS can be drawn from any space, but the required accuracy is still the distance between the figures, and it does not need to use the space that was used to draw LoS.

Accuracy and Attack Steps refers to the distance between the target and attacker, and Ranged Attack also talks about target, not target space.
