i’m a beginner with the particle system in ue4, and i want to emit particles in an fan shaped way. But i want also control how many particles are emitted in a specific direction.
For example: in X-direction i want to emit 10 /s , in Y-direction 50 /s and in -X-direction 20 /s. The amount of particles between those directions should be interpolated. All particles must have the same speed.
In other words i want a distribution of the emitter rate not over time but over the direction. If i could control this interpolation with a curve, that would be awesome.
I want to archive something like shown in the picture below.
P.S. Unrealengine is awesome, your tutorials in youtube are realy professional i want to say thanks for setting it free.
So In order to understand exactly what you want this particle system to do I need a little more information.
You said you wanted this to be emitted in a fan shaped way. Do you mean spinning around like a propeller. So the particles will emit at the same sped be at the same spot instead of an actual source.
Are you talking about a fan as in a semicircular way.
After some clarification I will be able to better understand exactly what you are trying to accomplish.
My english isn’t as good as it should be so i rendered a little graph in blender.
no spinning around; all particles must have the same speed;
The reason why it is so important for me to get exact this particle behavior:
I’m a german engineer at a university where i’m involved in the education of new engineer students. I want to visualize the radiation measured in the raman-spectroscopy-experiment for the students. And i also want to virtualize some other experiments with the UnrealEngine.
(I dont teach teach the UE4. I use the engine to teach physics in a new way)
So if the particle behavior isn’t correct, i’ll certainly get in trouble with some students
I tried myself a little bit more, and think i ll use something about 10 to 16 transmitters to “fake” the effect i want. All setup with a startvelocity of 100 in X-direction an a little distribution in Y / -Y of about 5 to 10.
Is there a solution to control the emitter rate by a blueprint? so i could setup a formula that calculates the different emitter rates out of my given curve.
But first i try to find tutorials about particlesystems and blueprints and only if it does not go any further i ll come back to you.
I 'm really excited about your support and again i want to thank you for your time spent on me.
