I've written a Line-Of-Sight system that uses a CollisionFree test inside a while loop.

It works well.

The problem is I want some actors to be see-through and others solid. I don't want to disable collision state on them either!

My current system is blocked by ANY actor.

I want to use an actor variable like "isSolid".

But...

If I change the x and y of a collision test actor inside a while loop will collision detection for that actor work for a range of positions? Or will it only detect collsion on a Draw Event.

Any feedback appreciated!

Further testing indicates that collision detection only occurs on a Draw Event.

Hmmm...

I need is a version of CollisionFree that ignores collisions where the collide actors "isSolid" flag is not set.

Having a lovely conversation with myself here!

Anyhow - I found...

Actor *getactor(long x, long y)
Returns Actor at position (x,y) (in game coordinates) if success, invalid Actor (with cloneindex = -1 and name = "invalid Actor") on error.

Would this return the actor at precisely the given co-ordinates or can the actor simply be touching them somewhere?

More testing!

Returns actor that collides with that point.

Yay!

I love the way that you think! Better yet, you share it with the rest of us.

Heh heh.

I sometimes I feel like Game Editor is a game itself!

We're not ignoring you Jazz! You posted the first lot within about half an hour - you are too quick!

I think that's a great contribution - thanks.

Thanks mate.

I am hoping to publish a Line-Of-Sight actor at the end of all this.

( At the moment I am being distracted by spring simulation! Too much fun. )
