Tracking in Geometry Nodes | Blender Tutorial

there are several ways for tracking in Geometry notes I'm going to teach you the more accurate and more efficient way to do that in this tutorial let's get started first of all we need two objects that can be anything you like I'm modeling an arrow for the instant subject here but you can use eyes needles face or basically whatever you like I leave this object at the center and I go to Geometry node workspace customize it by editing areas and I added a new geometry setup to my object I keep the group input and I add the grid node by pressing shift a and searching for it then I just add an instance on points node after the grid and I use the group input as the instances input I can change the size of the grid and increase the vertices of that to find a better look for my instances I also scale them down from the scale input now I'm done with the instant setup so I add the UV sphere to my scene to use it as my target object then I imported it to my node editor by dragging it from the outliner to the node editor after that I add a vector math node and I set it to subtract then subtract the location of my target object from the position field which calculates each instances position I use the result of the math for this rotation input as you can see it's not working because I need one more note that is called align Euler to Vector I just add it and I put it here I set it to z-axis and I make sure that I'm using the vector as the inputs and now if I move my target object by selecting it and hit G on my keyboard you can see the tracking effect is working properly I said everything about creating the effect so let me give you some tips the first tip is about how to make the instances in this case arrows to move up when the target gets near to them it can be done by adding a set position node after the instance on points node then calculate the distance between the target object and the instances position and plug this result into the offset of the set position after that add the combine XYZ node to determine which axis do you want the effect to be applied it's the Z1 in this case at the end at the map range to invert the effect and adjust its range the second tip is about how to randomize the location of your instances well you can either use a distribute on points before instancing to make some good variation using that node or of course you can add a set position node plus a random value as its offset to randomize the location in each axis but pay attention that you need to move the tracking setup after the randomization in order to make the effect work just add a rotate instance node and plug the setup into its rotation inputs and there we go the effect is working well and somehow if the effect is working inversely for for you just multiply the final number with negative 1 and you will be good the final project file is absolutely on my patreon and a shout out to all the patrons who are supporting the channel thanks for watching guys wish you the best and stay tuned for the next obviously by subscribing the channel goodbye
