Is there anyway of just removing any interaction between the weapon and the platform altogether? I can’t think of any reason why I would need the weapon to be able to interact with the platform and so I think it would be better just to remove it. Also, my problem with enabling/disabling collision is that, in theory, if the character swings their weapon at an enemy while jumping through the platform, the weapon will end up passing harmlessly through the enemy instead of dealing damage. I know you can create custom collisions as I’ve seen it in at least one tutorial video I watched on YouTube, although I’m not sure if that would be the proper way of going about removing the weapon/platform interaction or if it can be done with the preexisting collision settings.
Its one whole animation consisting of 15 frames with the Animation Notify for putting away the weapon on the very last frame. If by “move the notify further down the animation” you mean move the Animation Notify forward a couple of frames instead of backwards, then that’s going to be a bit of an issue since as I just said, the Notify is on the final frame of the animation & therefore can’t be moved further forward.
