This is just a quick idea that popped in my mind, but I know little to nothing about scripting, so it is just a suggestion. In PB, it is possible to display a HUD when aiming at an entity, right? Well, what if you displayed a regular crosshair but add some lines to a character's script so that when you are aiming at that enemy, it displays an image of that same crosshair, but in a different colour? This would be a cool effect to show when you are aiming at an enemy.

If anyone wants to try their hand at this, be my guest. I don't own PB, so I couldn't use it but other members might find it useful.

I don't believe it's possible to change the crosshair itself on the fly. But, you can hide the crosshair and display HUDs positioned in the center of the screen that LOOK like crosshairs. Then swap between them when aiming at certain entities.

Also, you could have it show a green crosshair when aiming at allies. And combined with weapon scripting (which, sadly, seems to be bugged right now) you could prevent a weapon from firing at allies.

I did the exact same thing in Alpha Project using the variable system and the pickobject=x feature in Project Blue.

So, it would be possible to add a little Text Hud showing "Machine Gunner" or "Sniper" or whatever if you aim at an enemie? Would look pretty cool.

Or even better, that way the player would be able to see the Name of NPC's like in RPG Games.

The concept I used is this:

If variable ch equals 1, set crosshair image to white
If variable ch equals 2, set crosshair image to green
If variable ch equals 3, set crosshair image to red
If variable ch equals 4, disable crosshair (handy for melee weapons)

using the pickobject command, you change the variable to whatever crosshair it is:

:state=0,pickobject=1:setvar=ch 1 (or something along those lines)

Using weapon scripts, you can even make the crosshair fade out and back in while reloading or down the sights.

It's only to bad the pickobject radius can't be defined because it tends to be a little finicky about where you are pointing on a character. Usually it's in the centerline upper-chest to neck area on characters that pickobject=1 becomes true. So looking at limbs or the top of the head won't always trigger the condition.

Technically this is doable in stock FPSC now but without PB's hudfade function it can look a bit buggy because your huds can strobe. Pickobject works best with small entities, like switches or pickups, in my experience.

@Plystire, That's what I meant, I must have explained it too vaguely

@Everyone Else, Well it's interesting that some of you have realized this idea too. I may try to implement this in my next game if I end up using PB or PG.

@Wolf:

Using Lewis' setup, you can have a multitude of variable values, and have specific enemies trigger different values, to display their class alongside the crosshair (which would be cool!) such as "Sniper", "Machine Gunner", etc. with your examples.


@Errant:

Unfortunately, administering an epsilon to the equation (giving it a "wider than pinpoint" area of detection) would take far more processing. At least, the way I would implement it. I'm not the greatest when it comes to collision calculations.

I wasn't aware of it's finicky behavior regarding characters. I'm not sure what could be causing that, without blaming DBP itself, since the command relies heavily on DBP commands to determine whether you're aiming at an object or not.

Hold on... so you're saying that there is NO WAY in Project Blue that we could have this amazing idea? Maybe do the color change thing, thet would work, but the names would be better than the latter.

What?

When did I say that you couldn't do it? I've only been saying that you CAN do it.
