hi people
i have a multi trace that goes into an Array, everything in the array is hidden, I am struggling to get the items to show when objects are outside of the Trace and is in the Array, I have tried a few things, but I can’t get it to work. well as I don’t understand how to only select the assets that are not in the trace and in the array as i can only get a reference that the array hits
I tried anther trace that is bigger than the first trace, then every object that is in the bigger trace and
not in the smaller trace should be removed from the array and not hidden, but I am struggling with the code.
I downloaded a marketplace asset to see how they do it but I doesn’t work that well and doesn’t hide and that well.
has anyone got a way to show the meshes,
More or less guessing here, but you could try to get all objects (of class) and then loop over the array to check if they are part of it and if the check is false you set the visibility to true.
Or set all to be visible and then make the array objects dissapear, but I’m afraid both methods are not to efficient.
What are you trying to achieve? Are all objects visible at the beginning, you make them dissapear in the array and then you want to re-evaluate if they are still in the array?
Maybe you could reset the visibility automatically with a timer, which gets reset when the object is still in the array. So at the beginning you drag of a clear node from the array.
edit: or is your problem that the objects are still in the array? Then the solution would be easy: you reset the visibility and then clear all objects from the array before you do the trace.
thanks for the reply
I probably should have been clear, when the player walks behind a wall or under an object. it hidden then after the player walks away from it is visible, I crated the array because I need to have multiple objects hidden at once, hear is the simplest version went back to witch works well for the hidden part, I am struggling with showing the visible part, if I have a few objects hidden I only want to show the parts that are not in the other trace with is larger ( the trace is just a trace that follows the player I don’t know if it’s the best way of doing it it’s just what a came up with but it’s not working anyway so any other ways i am open to)
i played around with occlusion masking but I could not control it as much as it would always hide other objects with I didn’t want to,
the problem once i figure out how to show what abject i want just remove it from the array then So on, or main version i have the player walking to a trigger box with make the Tace start or i load a stream level.
i just don’t understand how to get a certain object in a array so i can show it whiles other objects remain in the array until it is there turn, because i don’t know how to get the object reference, the trace only pics up what’s in the trace, witch is where I get the larger second trace from if the object is in the second array \ trace but not in the first array i want to remove that object and show the object
I’m having some problems following you, do you want the objects stay in the array and be visible, or do you want to remove them from the array and make them visible?

Assuming you want the first version (Make objects visible and remove them):
Before you do the Linetrace you make a loop over the array and make all objects visible. Then you drag of a clear node from your array. Now all Objects are visible, the array is clean (otherwise you will still have objects from the last trace in your array) and then you can do the trace and fill the array again, make the objects invisible.
-
Second version (Objects stay in the array, objects of second trace get visible):
If you don’t want to clear the array you can do the second trace and do 2 loops: The outer loop getting an element of the second trace, the inner loop would check if it is on the list and make it visible.
- You propably want to clear the array. If you dont clear it, the objects from the old traces will stay in the list forever. E.g. if your char is moving from one room to the next, all objects of the first room will stay in the array and be affected.
- To get a specific entry of your array you can drag a “get” node of the array and specify a number (starting from 0). You can also do this in a loop and compare the given elements to others.
Thanks mate
sorry I don’t understand what you mean which is my fault writing is not my strong suit. have you got an example of what you mean. i tried out what you said but it didn’t do anything.
yes, you are right I want to make the mesh visible and then i remove the mesh/Object from the array but like I said I don’t understand how to get or find the reference out of the array to remove it, when that mesh/Object is not block by the player
there are simple ways to do it, but it just relays on all the objects becoming visible after there is no object that is blocking the player. I want to control what objects are visible and hidden
