I have a cockpit type game, and just cant figure out how to get the crafts altitude reading.
Ideally I want it in the traditional sense like a sim with a some kind of Altitude meter bar that scrolls near a triangle Icon but I would also just settle for a Number value.
I intend to have this on an external view hud, cockpit screen and a main HUD like elite dangerous type right in front of the ship.
Whats is the best way to do this.

For the vertical bars you could shift texture coordinates of a material bound to a widget’s image.
Have a look at this crude example:
The widget’s Tick will modify *vPosOffset *variable and push it to the material’s parameter; the up/down direction is controlled through neg/pos ClimbSpeed var.
End result (it’s smooth in game):
The blue arrow could be hooked up to a map ranged ClimbSpeed and shifted about in the canvas.
The text, hm, not sure if that’s the best idea but you could have 3 text blocks and map range shift them in the canvas in a similar fashion. You could let them slide off the canvas and ‘disappear’ only to snap them back to the very top/bottom.
WOW Awesome stuff Everynone
I will Totally try this , Just need to get My ships height on the readout . I was wondering if a Line trace to floor would be the right direction.
Only if you are building a ground tracking radar. 
Altimeters usually display altitude above sea level.
So you could simply interpret the craft’s world Z value (in respect to your “sea level” in your map)
Sorry to bother you again Everynone
I have replicated everything in your example widget BP but just cant get the altimeter MID node to the set brush to material node like you have .
What is the Altimeter MID?
Everything I Tried after dynamic material instance to get to the set brush node, does not want to connect .
What did I miss?
Thanks
Thanks Im not really trying to bother with the full on sim of sea level. just looking for a very simple number value of my ships height from the main ground which I could set to zero Z location.
Try dragging a wire off the image rather than the material instance → type SetBrushFromMaterial, and then plug in the the material.
Right click the Return Value and PromoteToVariable - this will create a reference to the dynamic material you’ve just created.
The SetScalarParam you currently have is used in collections and cannot be used here. Instead, once you have a reference variable, drag a pin off and then Set Scalar Param
It all worked Thanks.
strange that nodes refuse to connect unless I created them directly from the nodes I want them to connect to.(Will have to remember that)
Only issue I have is I cant get the Image to connect to the set brush node .even by pulling it form the pin.keep getting Not compatible with border reference.
AS you can tell I’m still a BP noob
Ive checked and even deleted it and recreated the Image . but also all my other Images I have said the same thing when I tested them on it .
Strange
OK Found the problem
I tried to connect the image to the dynamic material node parent pin and it said it wasn’t compatible with images .(that told me it sees is as image) so i tried to connect it to the set Brush node again and noticed the node itself was saying that border was not compatible with Image and I figured that the set brush node was the issue . turns out there are 2 types
Image target type and Border target Type , they were named the same and I just chose the wrong one from the list.
got the right one now .
thanks for your help again your a Legend
