Probably missing a directive using or a reference to the assembly.

Glad you got it working. https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-35 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-35 Thu, 19 Aug 2021 09:01:00 +0000 So my solution is I'm following the exact code from the youtube link you give. It works fine too just like your code, except it does not give me any error warning. Though I prefer your code, maybe for now I'll stick with the one on the video. Thank you! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-34 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-34 Thu, 19 Aug 2021 07:49:00 +0000 Hi Jeff, no, "this" should not be required, it's mostly a convention. Just make sure that each slice is named the same in every image - so that each slice for player 1 has the same name as for player 2 and so on. Usually when I'm having trouble I just set a breakpoint on the offending line and start the debugger, inspecting the variables should definitely help in your case as well. https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-33 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-33 Thu, 19 Aug 2021 07:12:00 +0000 Hi Erik thanks for your reply. Well it's weird, I even test it by renaming each slice only with numbers (1 to 10) to make sure I'm not having a typo. The error is still there from the moment I hit the play button (still not interacting with anything in my game). I'm not using "this" in my code, don't know if it affects anything https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-32 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-32 Thu, 19 Aug 2021 06:33:00 +0000 Hi Jeff, strange if each slice is named correctly, but I think it still sounds like the problem that Dorian had above, check <a href="https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-2" rel="nofollow" target="_blank">https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-2</a> Hope this helps! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-31 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-31 Wed, 18 Aug 2021 13:27:00 +0000 And yes, I'm not "falsely" naming my sprite, because everything works.

I learn from your youtube , but when change sprite in Head and Body Sprite Render, it have problem is run change 1st sprite and not others. With multi spriteRenderer in one character, so I would like ask how is the best way to solve it? https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-24 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-24 Sat, 21 Sep 2019 09:29:00 +0000 Hi Tutmo, that's great to know, let's hope it helps John - or someone else for that matter. And happy to hear you found the post useful! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-23 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-23 Tue, 17 Sep 2019 17:39:00 +0000 Hey John, I ran into the exact same issue - all my Sprite names were unique per Sprite Sheet, but still getting the exception error. After debugging in circles, I realized the issue (for me anyways) was that my initial Sprite in the Sprite Renderer was set to 'None'. I just needed to set the initial Sprite to any one of the Sprites in my Resource Sprite Sheets and the error went away. Hope that helps. Thanks for the original post Erik! This was way clearer than anything else I've found after hours of Googling!! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-22 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-22 Tue, 17 Sep 2019 17:20:00 +0000 Hey thanks for getting back to me so quickly. I can confirm that within the sheet, no sliced sprites are named the same. Each has a unique name (Crowd_Generic_0, Crowd_Generic_1, etc...) So I am using the sprite swapping because I am emulating a large crowd (50+ NPCS). A crowd NPC is to use the same animation set, but I am swapping their sheets in order to avoid having to create unique animations over and over again for each NPC. So essentially 50 NPCs are in the scene - all at once - all referencing one "leader" NPC's animations. I appreciate the help! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-21 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-21 Mon, 16 Sep 2019 14:10:00 +0000 Hi John, probably, two sprites in the sprite sheet have the same name. Make sure each name only appears once ("walk1", "walk2"...). If you can't find the problem, try setting a debugging breakpoint in your code in visual studio. Then click "attach to unity" and start your game. Hopefully, stepping through the code will make the problem obvious. Hope this helps! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-20 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-20 Sun, 15 Sep 2019 07:22:00 +0000 Just to update - got it working - thank you! But I'm getting spammed hard in the console: ArgumentException: An item with the same key has already been added.

And with the above code, the sprite sheet should only reload once if changed on the fly. Let me know if you have found that it doesn't. https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-17 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-17 Tue, 10 Sep 2019 21:18:00 +0000 Holy hell thank you so much for this piece of code, you wouldn't believe how long I searched for something like this, it is exactly what I needed! One question - is there some way to make the sprite sheet change only once at the press of a button or does it have to constantly be in the LateUpdate function? https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-16 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-16 Mon, 09 Sep 2019 16:20:00 +0000 Hi Xenon, please check the answer above, Dorian had the same issue. https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-15 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-15 Wed, 14 Aug 2019 22:11:00 +0000 I did exactly what you showed and this came up KeyNotFoundException: The given key was not present in the dictionary.

Sprite next to sprite? [][][][][] < your sheet [] [] [] [] < my sheet can I have it like this? https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-13 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-13 Wed, 10 Jul 2019 17:29:00 +0000 Erik, thanks a lot for this, it is simply awesome!

Take a look at the first image in this guide. Click each sprite in the sheet and make sure the name is unique across the sprites in the sheet, such as "walk0", "walk1" etc. Then also make sure to name each sprite in the second sheet with the same name as in the first one. Hope this helps! https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-10 https://www.erikmoberg.net/article/unity3d-replace-sprite-programmatically-in-animation#comment-10 Mon, 28 May 2018 17:53:00 +0000 The code works perfectly, but the console keep showing this every frame: ArgumentException: An element with the same key already exists in the dictionary.
