Hey y'all, I felt like doing some keen modding related thing today so I decided to try to get the patch for changing the coordinates for the on map teleporters in keen 1 - to work. It is one of those tricky patches that aren't too easy to use until you figure it out. Anyway now that I got it to work...

The end game One of the important principles of level design is that for a level to be good it has to be winnable. The same also applies to a level pack or mod. If there isn't a finish line then playing it is less fun. Although each level when completed works as such a milestone. There should also ...

Chapter 9 Changing sprite size and hitbox management We have already seen that by using patches you can make it so that sprites when shot create another dying animation then they normally do. And sprites other than the yorp can spawn a stunned yorp animation. But changing these features without cha...

Thanks, I am considering opening another topic for this project when the mod is a little further in development. To discus the actual mod rather than the tutorial. I hope it won't be considered double posting, I guess I could first add more content before posting it there, then it technically isn't.

Even if it felt hard, it would've been easy to just place keen right on that spot before the jump in order to test this.

That's how I did it actually. The video is just to show that the jump is possible. I didn't walk through the level every failed attempt this time.

Chapter 8 Patching enemy behavior. In this chapter I will give some examples of what you can do with patching enemy behavior. Enemy behavior is relatively complex. And even if it is not that complex, figuring out how it works is not always simple. However there are a couple of key points where you ...

Chapter 7 Patching options for enemy traits. collision. Using neural stunner and changing text In the previous chapter I talked about changing the sprite type of sprites/enemies/npcs. In this chapter I will explain the collision trait. By patching the collision trait of an enemy and giving it the t...

Chapter 6: Patching options for enemy traits. Sprite type In Keen, enemy sprites, or NPCs in the case of yorps and others have certain traits that define how they interact with the player (keen). For example gargs kill keen on touch but yorps, butler bots and tank bots only push keen. It is possibl...

Chapter 5 Changing speeds, negative values and more patches I mentioned in the previous chapter that patches could be categorized based on how difficult they are to use. So in this chapter I will explain how to use some of the slightly harder to use patches. Some patches to work require you to chan...

Chapter 4 Some more patches bridges and more We have now set up the most important modding tools we would need to create a keen mod. Now that we know how to use CKPatch it has become relatively easy to add any keen patch we want to our mod project. Patches fall more or less in three categories. 1. ...

Chapter 3: Patching with CKpatch and using tileinfo We now already know how to change a lot of the game. We can build completely new levels. With the existing graphics or change it to entirely your own. Note that all these changes we can achieve without any patching. We didn't actually patch the ga...

Chapter 2: Changing graphics and levels Now that we have set up Modkeen to import and export graphics as needed we are now ready to actually change the levels and graphics. Level editing First we are going to start with opening level01.ck1 in mindbelt. Once you have clicked to open it mindbelt will...

Great idea! I started work on something like this more than 20 years ago but didn't finish it. Story of my life! Sometimes it is also better to just abandon a project if you aren't feeling it anymore. I also have done that before. What format is this going to take? Will you host your own website? D...

Introduction: Hello Keeners, For my next keen project I am planning to do a minimalist keen1 mod. a very short and basic level pack with some small graphical changes. But I am also planning to experiment a bit with patching. Now my plan is while I am doing this to also write a tutorial for keen 1-3...

I saw you made a wiki page. Thanks, the screenshot is also fairly representative of the pack I think. I assumed that all the maps were not added yet because you either didn't have time for it or you didn't want to get spoiled yet. Very valid reason ofcourse. Yes, as I said before I agree that the la...
