For anyone not lucky enough to play this yet, the hud mfd could be toggled to show a rear view. Any possibility in a future build? (For low spec pc's would it be possible to make it use lower lods?)

[chief1983]

Like a reverse camera in new cars?

[Colonol Dekker]

Yes but toggleable.
(Can't believe that pimp my ride ripped off the confederation )

[Flaser]

Nuke already implemented something similar and more.
Using scripts and rtt he made a turret display and even an input method to control said turret.
He could easily make your rear-camera...


....now if only people helped him test the darn things!

[Colonol Dekker]

I'd be happy to.
Just point towards a "how to"

[Nuke]

i havent checked the state of rtt at all lately. it might not work anymore. then again it might work uber cool

[WMCoolmon]

Tested, looks great.

The default key to turn it on and off is "Alt-v"

Code: [Select]

#Conditional Hooks
$Application: Freespace 2
$On Mission Start: [
if not g_RVTexture then
--Switch to turn rearview on and off
g_RVEnabled = false

--HUD gauge info
g_RVHUDLabel = "Rear view"
g_RVHUDXPos = 100
g_RVHUDYPos = 200

--Texture/camera preferences (must be power of 2
g_RVTextureWidth = 256
g_RVTextureHeight = 256

--Default texture and camera instances for rearview camera
g_RVTexture = gr.createTexture(g_RVTextureWidth, g_RVTextureHeight)
g_RVCamera = gr.createCamera("Rear view")
end
]

$Application: Freespace 2
$State: GS_STATE_GAME_PLAY
$Keypress: Alt-v
$On Key Released: [
g_RVEnabled = not g_RVEnabled
]

$Application: Freespace 2

$On HUD Draw: [
local ship = hv.Self

local ori = ba.newOrientation(0, 0, 0)

--Set camera to back of ship
pos.z = ship.Class.Model.BoundingBoxMin.z
g_RVCamera.Position = pos

--Set camera to reverse of ship orientation
ori.h = math.pi
g_RVCamera.Orientation = ori

--Set camera to be current camera, render, reset
gr.setCamera(g_RVCamera)
gr.CurrentRenderTarget = g_RVTexture
gr.clearScreen()
mn.renderFrame()
gr.CurrentRenderTarget = nil
gr.setCamera()

--TODO: Save previous camera and
--set previous camera when done

--Set HUD color
gr.setColor(0, 255, 0)

--Show a hud label
gr.drawString(g_RVHUDLabel, g_RVHUDXPos, g_RVHUDYPos)

--Offset the texture/box appropriately and draw them
local x = g_RVHUDXPos
local y = g_RVHUDYPos+gr.CurrentFont.Height
gr.drawImage(g_RVTexture, x, y)
gr.drawRectangle(x, y, x+g_RVTextureWidth, y+g_RVTextureHeight, false)
end
]
#End
EDIT: Requires C09032008 build to work. I will be changing that "camera.Self" thing to "camera.Host" to match it with the SEXP jargon, but that should be a quick search-and-replace when it happens. Also, I'll add a current camera variable so this won't screw up cutscenes using the camera code.

[Colonol Dekker]

  Great :yrd:


I'll wait until you do those things that i don't understand before i DL and try it just so i don't have to DL two .exe's. Thanks WMCoolman.

I will be changing that "camera.Self" thing to "camera.Host" to match it with the SEXP jargon

The only time I've noticed the word host used in the code is to denote the first player to join a multiplayer server (Which is the player hosting the server except for standalones).

[WMCoolmon]

That's still not what I used for the SEXP. I'm open to suggestions.

[karajorma]

I'm not saying host is a bad choice, just that I've never seen it used in that context. Is there another SEXP that uses host?

[WMCoolmon]

Not besides set-camera-host, according to my SEXPs.html from 9/4.

[karajorma]

Ah. I get you now.
