I can drawing line with line renderer. But i want to pull that line with realistic effect like vacuum cleaner cable.
video (for 5 sec)
I want to connect all the parts to body part with drawing a line. After than, they should unite with visual effect. (like vacuum cleaner cable)
I just don't know how i can make this physics
example scene
Try this :

and then Position should be the middle of the object 1 and object 2 that you want to connect.
Click on one object (pos1) with raycast
click on 2 nd object (pos2) with raycast
Now you have their positions and objects selected
connect them (i don't know how you want to be the connection)
or do it manually
separate codes for every connection

I just started (yesterday) using unreal engine and I need to simulate a drunk character using BPs.
I'm using two camera shakes (one for standing still and one for walking) but I want to add some "displacement" on charater when he's walking.
Basically I want to define a random float to be added to X axis location in order to make character wobble smoothly.
It will be acceptable even if there's a way to make the character move along with the camera when it's shaking.
What I tried until now is using AddActorLocalOffset and a timeline to lerp between actor's location and actor's location+offset, but both are very choppy to me.
Maybe it's a noob question but as I told I'm very new to this and need it for a quick work.
Any suggestion?
Thanks
If you are targetting physically correct model, you should use AddForce (UE Docs). But this approach would require implementation of a "drunk animation" where your character will modify it's movement animation to "compensate" this force by stepping aside etc.
Another (much more simple) approach is by using AddMovementInput. This example can be seen here: UE Aswers. In this case, you are basically simulate player's input by adding small amount of side force here and there.
I have a death transformation for one of my GameObjects which goes from a spherical ball to a bunch of small individual blocks. Each of these blocks I want to fade at different times but since they all use the same shader I cannot seem to figure out how to make all of them not fade out at the same time.
This first picture is the Spherical Ball in its first step for when it turns from a spherical ball to a Minecraft'ish looking block ball and to the right of it is one of the blocks that make up the Minecraft'ish looking ball shown by the red arrow.
Now this is my Inspector for one of the little blocks that make up the Minecraft'ish looking ball.
I have an arrow pointing to what makes the object fade but that is globally across all of the blocks since they use the same shader. Is it possible to have each block fade separately or am I stuck and need to find a new disappear act for the little block dudes?
You need to modify the material property by script at runtime, and you need to do it through the Renderer.material property. When you access Renderer.material, Unity will automatically create a copy of the material for you that is handled separately -- including getting its own draw call, if you care about performance. You can tell this has happened because the material name in the renderer will change to "Materialname (Instance)".
Set the material's fade property using Renderer.material.SetFloat() (or whatever the appropriate Set... function is). Unfortunately the property's name isn't "Fade Factor". You can find the property's name by looking at the shader script, or by switching the inspector to debug mode and digging through the Saved Properties array for one that looks right.
The concept that I am talking about is similar to the style of game seen in many minimalistic, popular mobile games such as Color Switch, the Line Zen, Phases, or Bounce. These are endless games composed of a series of "levels" or "rooms" that are placed in a random order, and are one after another, creating the effect of an endless game. The key thing is that the challenges in each level are not random, they are drawn up before, and if that certain level is chosen randomly, it appears on the screen and the player moves through that level.
I think this concept might be called procedural generation, though I'm not positive.
How would I do this in SpriteKit using Swift? I'm not really sure where to start, maybe create a function for each level segment and, every few seconds, choose a random one to put on the screen?
Any help is appreciated!
Thanks so much!
Procedural generation is the name of the concept you are describing.
The approach will change a bit depending on the type of game you are trying to make but let's look at procedural generation in an infinite runner game. What you want to do is set up a buffer of level segments. The total size of the segments in your buffer should be at least twice the size of the screen. Every segment should be a child of the same segments node and they should be positioned so that each starts right after the previous one ends.
When a segment moves off screen (the player passed it):
remove that segment from the segments node
initialize a new segment (probably from a sks file)
add the new segment to the segments node
position it behind the last segment in the segments node.
The logic you use for choosing the next "random segment" is up to you. It can be truly random or you can fine tune it for the best user experience (avoid repeating segments, avoid segments that would ruin the flow, etc).
The key is to remove segments as they go offscreen and add a new one at the end of the buffer. This must be position based, not time based (time is less reliable even when the game scrolls at a constant speed).
I have player,as shown in the image on a bridge.I want his movement to be restricted to the bridge.(at present he can run outside the bridge in air).How should i achive this.?
1 method i have thought of is to use use continous collision detection between the bridge and the player,to check if he stays within the area.is this the right way to approach?and are there any other alternate ways
Continuous Collision Detection isn't strictly necessary unless it's moving really fast.
I see to way:
Use 3 collider: one for the player the other 2 for limit the sides of the bridge. This way the player can't compenetrate colliders and won't fall dawn.
Manually check inside input handling function that the limits of player movements (since the bridge has a simple shape, it shouldn't be difficult)
I am a straight noob. Everyone else says it, but I'm dead serious.
My question is, what is the best way to make a power meter to move a object? Meaning, how to set it up so that the longer the player holds the more power they get. Also how, would I incorporate physics?
What I'd like to accomplish is to have a player holding onto something so that when he taps on the screen and hold he powers up, and when he lets go he throws the object a certain distance.
just checking if the there is any thouch sequence or not is rather an easy thing, you just have to overload two functions for your scene class, one to inform you whenever a touch sequence begins and one to tell you touch is ended. the source code example is describe in this link. after than i think you need a gauge to show how much power is gathered so far, the easiest way is to use a texture with full power shown in it and the set it as texture and then show it little by little as the power goes up just as the code below:
// to create the gauge with zero power
CCSprite *s=[CCSprite spriteWithTexture:[CCTextureCache addImage:#"gauge.png"] rect:CGRectMake(0,0,0,10)];
// and then whenever the power changes you call this method
[s setTextureRect:CGRectmake(0,0,power,10)]
note that in my code i am using a 100x10 texture (power is somthing between 0..100 and texture height is 10 as the last parameter in both CGRectMake functions)
