if this is in a function being run previous will always be 0.0 as that's what you're setting it to at the top. The "quick" solution is to make previous "static" so it persists between function calls. From context though it looks like the accel is a member value of a class you're calling this from so a cleaner way to do this would be to implement getter/setter functions and update your previous/delta values there when it's changed. (depending on what you're trying to do)
I feel more confident and ready to make a Sci-Fi adventure game. My result of studying the Unreal Engine for May 2024, the 3rd month of the transition from Unity to Unreal
Today in Unreal Engine 5, I finally did it… Niagara System on GPU without event collision. I transfer the position of the collector to Niagara, calculate the distance there, and through the Export Particle Data to Blueprint module catch the supposedly collision, which I count as a particle collected, on the emitter side the Kill Particles module does a similar check
@mehdi_benadel I don't have any experience at all, I've been learning the engine for 3 months, but simple complex things can be done with simple approaches... I agree, writing custom modules in Niagara is difficult
New experiments with Unreal Engine 5, Niagara. A prototype of a magnetic device for collecting various bio material. I have a lot of gameplay ideas where it can be used and how: plants, insects, crafting, fuel or things to scare away creatures... Maybe you will have ideas too?
@jzillw Yes, that occurred to me too, it can also do it, but for this it is necessary to transfer the information of collisions between niagara and the blueprint, but I would do it in a different way, through decals and render texture
Similar mechanics can be done without the use of Niagara. According to the principle of a gravity tool, as in Half-Life 2. Check the collision over a large sphere, then transfer the force to the objects to move to the tool point. Check another collision (small sphere) to stop physics objects and make them children. When the effect of gravity is turned off, enable physics for objects and change the parent
After 3 hours, after 5 time crashes of Unreal Engine - I did it. Chaos Flesh wheel... my video card said - let's finish this quickly, because I can't take it out anymore. As far as I understand, it is not need in the game, but to create a trailer to show the rover - yes!
@maxim Looks far less disturbing than I was expecting a Chaos Flesh Wheel to look, but maybe the old Unreal meat cube demo made me think it was going somewhere else :P
Experiments with Niagara... Collision and difference in the reaction of the protagonist and other objects. Maybe you will have ideas what it can be in the game (gameplay)
My rule when studying is to do something small every day, especially in the direction you understand not very well. For me, shaders are an unknown world, so I try to recreate something every day
I'm thinking of using it somehow... Visually, a particle can be anything. The main logic is that the particle sticks to the surface and stays for some time
@maxim My special gift is making charming simple ideas complicated 😹 , so I'd be interested to see the particles bounce off different things and be changed different ways (so look different when they stick after). Not really helpful, sorry!
En materia de #videojuegos estoy probando la nueva versión de #Multiversus.
De momento crashea o se queda bloqueado en la primera pantalla de carga, con los ventiladores del PC empezando a girar a toda velocidad. Con otros juegos que usan como este #UnrealEngine5 también me ha pasado, pero insistiendo mucho terminé por lograr hacerlos funcionar.
Ya veremos con este. Se habla bastante de micropagos abusivos en el juego, y eso unido al uso de motor hace gracia que los devs se llamen Players First.
Suficiente señal debió ser que esta nueva versión tampoco funciona en #Linux, y si un juego a día de hoy no funciona en Linux ni con la versión de #Proton de Glorious Eggroll es porque trae algo que ningun juego debería llevar.
Los devs deberían llamarse Players NosLaSudan.
Today I decided to do nothing but build mechanics and learn the Unreal Engine, hence the many posts... hope you like the result. I took the animation from mixamo and made the material for the energy field
It has become a little better, in addition to the line, I also draw a sprite in the coordinates of the object. I will adjust the animation later... I may also add Font Material
I don't know what the design will be yet, I'm just making logic... maybe it will be a combination of design from games: Death Stranding, Starfield and Watch Dogs...
Tips / info gameplay will be divided into several options: a permanent marker over the object after scanning, a marker when crossing the object with partial information and detailed information about the structure of the object after its inspection (what materials it contains)
I started prototyping object tooltips, two simple animations and a redraw method that uses OnPaint function, in it I used Draw Line node, to be continued...
Bug in UE 5.3... I have 2 animations in the widget, I play these anim from the character blueprint, the node of a specific anim is displayed correctly, but when I output the name through PrintText, it show me the name of another animation. So I have to use hide panel for show
