Hello everyone ! I’m a french video game student and i have some issues with how to set up start and end point of a spline by adding more points in realtime. I hope you will be able to help me understand the logic behind my problems.
In a 3D platformer you control a character who can spawn clouds and use them. I would like to make a rain cloud who can draw water on the map by using a spline in realtime.
When you use the ability, the third person character is unposses. You now posses the cloud. You can move the cloud, the cloud is a pawn.
A line trace check the impact point to spawn a spline actor while the rain cloud is active (a spline component and a static mesh or spline mesh)
After the spline actor is spawned i want a new spline point be added every X tick. In order to create a water path.
It’s the same spline as in this excellent tutorial video Unreal Engine 4 Road Tool in Blueprints with Spline and SplineMesh - Part 4 Road Tool - YouTube
[PROBLEM 1 ]
the spline points that i add dont seems to be add or recognize by the start point of the primary spline actor.
[PROBLEM 2 ]
I miss some logic concerning where the add spline point node must be placed.
At best the spline actor is spawned multiple times with no links between them.
Spawned spline actor Event graph Blueprint
Spawned spline actor Construction Script
Rain Cloud Pawn Event Graph
Every components are set as movable.
The spline works perfectly in editor. (rotation, tangent calcul, spacing, new points adaptation)
But not in realtime … T_T
I’ll be happy to discuss about possibilities of adding new spline points of a spline actor in realtime.
Thank you so much !
