This was a GODSEND of a video! I've been looking for a radial bar for AGES and after two months of searching for something to replace my progressbar readout, I was about to move onto a different task when this video just saved my project's life! 😲
Ok for anyone having problem with progress bar variable, instead of changing the percent value (Use SetScalarParameterValue inside NewWidgetBlueprint's Event graph. And Target= Testbar > ProgressBar, ParameterName = Percent.) I wanted to give up on figuring out this but i got it after a break, so i'm helping other out too.
The difference between Mask and Translucency is much more complex than "sharp and smooth". Masked only allows full values of 1 (White, visible) and 0 (Black, not visible). That is why you get pixel edges cause smoothing usually is done using transparency which allows values between 1 and 0. But the cost is a lot higher compared to Masked, thats why masked is used for lots of stuff like fooliage (if you are not using SSS). However you can have low cost and smooth edges using the Masked mode by using the DitherTemporalAA node.
@@NiceShadow You put it right before plugging it into the Mask channel. However the smoothing when using Mask mode combined with DitherTemporalAA comes from Temporal Anti Aliasing, which is done in screenspace. That is why it will most likely not work on userinterfaces since they are rendered on top of the screen. You can still use it for pretty much anything else you'd like to or whereever transparency is taking too much computational power. ua-cam.com/video/kvHh0Jd-D3Q/v-deo.html EDIT: When trying to sharpen or smooth edges on transparency channel (this does apply for UI too) you can use the smoothstep node instead.
@@NiceShadow You need to play with the Max value. Increasing it to something like 8 or even higher will smooth it a lot. Smaller values than 1 will sharpen edges. Make sure you use it on single channels only.
Очень полезно! Правда я немного доработал твой метод и сделал немного по своему. Я считаю, что это надо делать не в функции, а в event-графе. Тогда работает
This works great. However, i am unable to adjust the Pecent variable in a different Widget's event graph. I can slide it manually on the right in the designer, but i dont know how to set the Percent variable on event.
Thankyou for the tutorial. Do you know what I can do if I don't want it to be a circle though? I still want to use the radial progress effect, but I want it to fill a different shape like an octagon.
Had this working in 5.0 can't get it working in 5.3. Whenever I reference the material in the image and compile it loses the reference and defaults to a non-existent material. Anyone ever see this before?
Using 5.1.1 and having the same problem. I set the default value in the instance to 0.25 and now I see the widget, but I can't dynamically change the default value in the whole canvass widget. It seems like the promoted variable isn't updating the image somehow. I also don't see the widget on the screen. I'll update if I figure it out.
One issue I had (probably not yours) is that I named my parameter in M_RoundProgessbar (the class, not the instance) as "Percentage" instead of "Percent" and so it was not updating.
I had the problem that I actually fix with removing the "Set Brush from Material" in widget graph. It seems that do weird things with Image Brush configured in designer... (Override brush vs material instance brush conflict)
I was also having the same issue. The fix was to replace the "Set Brush from Material" node with a "Set Brush from Soft Material". Oddly, it does not show on other widget blueprints when called in Pre-Construct, but when the widget percentage increases in Play Mode the progress bar works as expected.
Hi, thanks for this, this is really useful :) Quick question, I can see that you can change the rotation angle etc, but what would you change/add if you wanted to enable a parameter to change the direction in which the bar fills/empties? At the moment, the default behaviour, from a full bar (percentage 1.0) is that if you reduce this number, the bar reduces anti-clockwise, if you start from an empty bar (percentage 0) the bar fills in a clockwise manner. So, how could you reverse that behaviour (ideally as an optional parameter)? Thanks in advance, and again, for this tutorial :)
how can we use the scalar parameter value in another blueprint like the main character blueprint, to be updated on the tick. I had this widget percentage that was being updated based on distance for a progress bar, i just need to be able to use that value from the material. how ?
You need a reference to this material instance in your character. So create a 'Material Instance Dynamic' varibale in your character. In the widget on event begin play you need to create the material instance, save it in the variable and apply it as brush as I show in 7:20 (so make sure that it is created on event begin play and not in this SetPercent function). Then after that also on event begin play cast to your character and set the material instance dynamic variable you created in there to the variable RoundProgressbarInst. Then you should be able to adjust the parameter from you character.
@@NiceShadow i did it differently, i created a float value in the character blueprint where the logic was implementated, cast on the tick in the widget graph to get the character, from there i can use the image i was using and set the scalar parameter value to the float i was using from my character, it does work now. it works now.
Create a new material and check if you can change the domain there. If not you probably have a problem with your engine and you should consider to verify your engine in the engine overview in the epic launcher
I don't have a tutorial for a health system yet. But you should find tutorials about how create a health bar where it is connected to a normal progressbar. It should be very easy to use my SetPercent function instead.
@@NiceShadow its not very easy to bind to a health or magic or stamina value can you please make a tutorial for binding your setpercent to a value of the third person im very lost i have my stamina drain the bar pops up but doesnt link to my stamina no matter what i seem to try
@@magegames6202 Try the approach I answered you in your first comment. Alternatively you can also call the SetPercent node at the place where your stamina variable is setted. So casting from there to your ui and further to your progress bar to directly change the percent.
@@lawrence2598 When you create the larger widget that contains the Progress Bar widget, promote that to a variable. Let's name it 'Game Overlay Ref'. In the Game Overlay widget blueprint make a new function. Name it 'Update Progress Bar' and give it a float input. In that function, get the Progress Bar widget variable and drag off the "Set Percent" function that it contains and feed it the desired float value. Now, all you have to do to update the widget, is use that "Game Overlay Ref" and drag off the "Update Progress Bar" function.
@@CT-td9mt I have tried your method multiple times but i cant seem to get it to work, im making a round progress bar that shows stamina. The stamina code is fine because i have set up a test progress bar. If you could list some possible issues or give me something to dm you on that would be greatly appreciated.
Answer from another comment: You can run SetPercent on EventTick. To save performance you should create another float CurrentPercent. So that you only Update the material instance if the CurrentPercent != the input percent. That would have the same result as binding and for sure no measurable difference to normal binding.
@@NiceShadow Yeah i found what you said but I couldn’t figure it out :( I know I was somewhat close to making it work but I just couldn’t. Only been working with unreal for a few days still learning!
@@magegames6202 I think I solved this. I was also doing a Stamina tutorial. You will update the Stamina using the Event Tick for the whole screen widget you have (mine is called StaminaWidget_BP.) First, I added WB_RoundProgressTest widget to the widget canvas panel layout in the Designer view. (Similar to the video at the Outro chapter at 10:56.) Then in the Graph view, I now have WB_RoundProgressTest as a variable. Drag this variable into the graph and choose GetWB_RoundProgressTest (the only option). From the EventTick, I drag a line and choose "Set Percent". Connect the WB Progress Test to the Target pin. Now drag from Percent and choose the function GetProgressBarStaminaPercent to connect to the percent variable. And that did it for me!
I have 3 questions and I'm sorry they are, I'm a bit new but I learn fast and I would like to know about these three questions. Here are 2, and if I wanted to add a background to show the missing health and a curvature like in Kingdom Hearts, how would it be? and the third, how could you show the maximum capacity of life?, as seen in the Re4 Remake where you see a small line in life that indicates the maximum amount that can be obtained, I am not referring to the amount of life current max, if not full health thanks to yellow herbs, thanks in advance!
1. Create another material instance like in 5:55 but set in it the percent on 1 (or 0.75 related to the 2nd question) Then in the widget designer where you've added your progressbar, you can right click on this widget element and wrap it with an overlay, so you can put an image (where you select the material instance that you've just created) below the existing progressbar. Then you can tint the background progressbar black and reduce the Alpha. 2. I guess you mean that the radius shouldn't be 360°, it should be like 75% - in that case, in the SetPercent function, do not directly connect the Percent float with value of this SetScalarParameterValue node. put a lerp node in between. So the Percent from the starting node of the function would be connected with the Alpha pin of the lerp node, for A you're taking 0 and for B you would take 0.75 and then connect the result of that Lerp node with the SetScalarParameterValue node. And if you want to decide from where the progressbar should start to fill up you can easily do that in the transform settings if you select a widget element in the design tab - so adjusting the angle. 3. idk you probably would need put a third thinner progressbar in the overlay.
@@gaetanlancelle1173 you can make this event based instead of binding, anytime you take damage or heal, call this set % function. you have to add two float inputs for current health and max health. then divide current/max hp(etc) to get a ratio 0-1 value. you can add an f interp to node to make it smooth by getting the material % scalar parameter plugged into current, and the hp ratio as target. should set the interp speed to something a lil higher to not have lag, like 2 or 3
