Need Help With GuiSpeedometerhud

by james burch · in Torque Game Engine · 01/22/2015 (5:13 am) · 4 replies

Hello , again , hope youve been doing well ,

TGE 1.1.2 DEMO
I do not own the source code .

I cant get the needle to display for the GuiSpeedometerHUd .

Im assuming it is handled rather like the health and energy huds in the demo where very little scripting is involved .

Im having no luck at trying to display the needle .

I only want the hud while mounted to the default car , after blahblah::onmount , and deactivated onunmount .

If someone would describe the technique for displaying the needle or hud , I Thank You .
and have a nice day .


EDIT i found this in a search (this time for guispeedometerhud instead of just speedometerhud or speedometer etc...
===============================================================================
===============================================================================

void GuiSpeedometerHud::onRender(Point2I offset, const RectI &updateRect)
{
static char buf[256];

// Must have a connection and player control object
GameConnection* conn = GameConnection::getServerConnection();
if (!conn) {
return;
}
ShapeBase* control = conn->getControlObject();
if (!control || !(control->getType() & PlayerObjectType)) {
return;
}

Player* player = static_cast<Player*>(control);

F32 speed = player->getVelocity().len();

// Background first
if (mShowFill) {
dglDrawRectFill(updateRect, mFillColor);
}

if (mIsMetric) {
F32 displayValue = speed * 3600.0 / 1000.0;
dSprintf(buf, sizeof(buf), "%s%.1f kph", (displayValue < 10.0 ? "0" : ""), displayValue);
}
else {
F32 displayValue = speed * 3600.0 / 1609.3;
dSprintf(buf, sizeof(buf), "%s%.1f mph", (displayValue < 10.0 ? "0" : ""), displayValue);
}

// Center the text
offset.x += (mBounds.extent.x - mProfile->mFont->getStrWidth(buf)) / 2;
offset.y += (mBounds.extent.y - mProfile->mFont->getHeight()) / 2;
dglSetBitmapModulation(mTextColor);
dglDrawText(mProfile->mFont, offset, buf);
dglClearBitmapModulation();

// Border last
if (mShowFrame) {
dglDrawRect(updateRect, mFrameColor);
}
}

==================================================================================
==================================================================================

So... for me as a noobish type , How do I assure
// Must have a connection and player control object
GameConnection* conn = GameConnection::getServerConnection(); //

sorry if i make little sense , also this is the only reference i could find .

    Hi , and welcome back , I have not been successful here . Ill demonstrate my analysis skill . Im guessing that the 2 variables that the fuction needs are the control object and speed !? Okay , can anyone tell me what the 2 variable that the guispeedometerhud needs in order to do its thing ?:). My limited understanding of the server client leaves me doing a good bit of guessing that hasnt worked . I seems to me to be all doable on the client side , but I think that i understand it to have need for a connection to the server scripts . I see , if no connection return , but what , I have no connection ? Sry , just dont get it . Any advice appreciated :) Thank You .

    BTW It seems like a cool little GUI which could have many implications besides control object velocity , and So i still would like to see it functioning Cooly .

    Hey James,

    Are you using the SpedometerGUI in a FPS context (i.e. with a FPS player attached to a mount-point on the vehicle)?

    If so, there is a problem in the C code in the version of Torque you are using. The code you've posted above has been updated considerably since 1.1.2 (and 1.5.2).

    {Note: It's been a LONG time and I don't have my code handy, so I might be off-base on the details} Basically, look at the top of the function where the code does a dynamic cast to shapebase and then checks to see if the object is a player. The 1.x code does a dynamic cast to *vehicle* and then dumps if the cast fails to produce a valid object. It works fine in the Race demo because in that context the player *is* a vehicle. I can't remember if the routine just dumped or if it failed trying to get a velocity.

    I fixed it engine-side and didn't think about it much beyond that. IIRC, my solution was similar to the function you posted above. Unsure if there's a clever way to work around the issue in script or not, but that's probably what you're dealing with.

    Mr. Butler,
    Ive at long last got to see that cool little gui thing work . Its everything I imagined :) . Thank you very much , alas I do wish to use it in the FPS context . Im guessing now that there may be no way to compensate for there being no vehicle controlling object ... as , as you say , it appears that it will "cast" to Vehicle in shapebase in engine whenever the speedometer gui is called ... btw I think that that IS your code above . coool tho THX :)

    Well , I can change the control object of the client from the player to the vehicle and it works in the FPS demo .
