What is the smart way to make a blueprint that animates a bridge of steps into place? I don’t want to do it as a block but rather as a rolling motion for several blocks.
The method I’ve tried for now looks tedious and maybe computationally expensive.
You can do it with an array of components, assuming this is all in a blueprint.
One timeline, and an array of components on the update pin.
Tell me if you need more info.
I guess I’m lost as to how to make an array with offset timing for the animation. (to make the movement of objects roll in a uniform way.) If I use a delay, it just delays everything evenly.
Are those steps supposed to animate one at a time? Or are there multiple steps moving at the same time?
Rolling piano chords. Not all the keys are pressed at once. (not my video. hopefully the analogy makes sense.)
I could do something like this. But this is ugly and I have to make a bunch of duplicate float tracks that are all offset. And if I have 30 objects… That is also tedious.
Normally, you would have 1 float track, and use lerp to move the object. That way, you can keep stuff that changes, out of the timeline.
I’m pretty sure what you want can be done procedurally, ie without having to store coordinates.
Is the rippling keys of the piano what you want, or is it something else? ( before I code something up ).
The thing is I was going to have a variety of rippling effects. Are you suggesting this can be done with construction scripts? Here is another video that might be helpful. (notice how the objecs are rotating freely before they lock into place. But they get sent back and start rotating freely once mario moves away.) So it is two things. The path can assemble itself as the player progresses. So the player controls the pacing of the assembling of the bridge. But at some point. The difficulty of the game increases and the player is no longer controlling the pacing of the bridge being assembled. That the game then assembles the bridge at a predetermined pace and the player just has to keep up with the pace of the assembling of the bridge. So I guess…
Easy Bridge level: Player based pace would just be lerps based on distance from the bridge piece?
Hard bridge level: Should I take the Easy bridge level and instead using the player position have a custom animation null object that runs through easy bridge level to facilitate the automated assembling process of the hard bridge level? (sorry I’ve been so difficult to explain this.)
Just to share ideas:
Change the trigger overlap to take another actor and move it through a spline so that the player has to follow its pace (but player wont see this actor).
e.g.:
For the “hard” bridge:
This is just to get it working… you could save yourself the each instance with a timeline and have 1 actor manage all the lerps and hovers, but that tales a bit more time to put together.
Yep, I was thinking of this same thing. Using overlap in combination with move component. I don’t know if “move component” is the right way to do things. But that is what came to mind when CWO mentioned “lerp”.
Delays don’t work well inside loops.
(out the top of my head) If you want to make it work so that a single actor manages the transitions, I suggest considering the following:
The way it would work is:
Now, in c++ you can use custom float curves without timelines. Don’t remember if you can access their values in bp without a timeline node.
As alternative if you want all platforms to be in the loop and offset activate them from start → last with a delay: you could use MapRangedClamped.
Here is a quick example creating a zipper:
