Today I took a day off, so no progress today.

[Game of Purpose] Day 80

Today I played around with importing landscapes from real world height maps. I used https://manticorp.github.io/unrealheightmap to get the assets, but when importing the map looks really uneven. I don't know how to smooth it yet.

[Game of Purpose] Day 74

Maciej Sawicki — Wed, 31 Jul 2024 22:03:19 +0000

Today I played around with a headshot animation and I made it work with State Aliases. However, I feel like I don't have enough knowledge and experience to make a realisticly behaving character model, which also reacts to physics shots. I think I need to make some basic animations, such as: walk, run, move damaged and death and move on to other parts of the game.

[Game of Purpose] Day 73 - Improving animations with Blend Spaces

Maciej Sawicki — Tue, 30 Jul 2024 23:07:59 +0000

Today I improved walking animations when hittin legs.

My Animation state machine became cleaner than yesterday, because I used Animation Blend Space for animation between running<->walking<->limping right/left.

It takes 2 params, SpeedPercent between 0 and 1, where:

0: standing still
1: running at full speed

It also takes LegInjury between -1 and 1, where:

-1: left leg fully injured
0: no leg injuries
1: right leg fully injured

A problem I can see right now is that when falling down players capsule is still standing still. Don't know how to make it fall with a skeleton, yet.

[Game of Purpose] Day 72

Maciej Sawicki — Tue, 30 Jul 2024 00:23:15 +0000

Today I worked on animations. I learned what a Conduit node is. I have yet to grasp the idea of what a State Alias is, but we'll get there.

So I made a Swat limp when hit on leg. When hit on a left leg it limps on that leg and the same for the right leg. When hit on both legs it trips forward.

One problem is that tripping animation on Mixamo is not "in place", so it throws itself forward. Yesterday I found an addon in Blender, which makes it "in place". I tried that, but unfortunately when importing animation back to Unreal the axes are mixed and the pivot point is also broken.

[Game of Purpose] Day 71

Maciej Sawicki — Sun, 28 Jul 2024 23:33:54 +0000

Today I played around with Animation Blending. I want to change how the SWAT model animates depending on their HP.

I made an Animation Blueprint with the following state machine:

I made an Animation Blend Space for a Walking Animation and did Crawl and Death states for the other animations.

It turns out that on Mixamo.com when you download an animation it takes into effect the sliders values. I wondered how you can play around with them in Unreal, but you would probably have to download 2 separate animations with different slider values and make a Blend Space for them.

I also learned that you should download "In Place" animations from Mixamo, because root motion doesn't work. I found a reddit post where you can take an animation with a root motion and make it "in place" in Blender with a plugin

[Game of Purpose] Day 70 - Animations Viewer Map

Maciej Sawicki — Sat, 27 Jul 2024 23:33:46 +0000

Today I made animations viewing map. I wanted to look at all the animations at once and decide which one to use. Here is the result

Each demo skeleton has a text above representing which animation it uses.
Texts were overlapping and I didn't know how to wrap them yet I created 2 rows and made the alternate.

I create it in a separate blueprint, so that I can easily instantiate it with a Spawn Actor From Class node.

To instantiate that blueprint in a column/row manner I used modulo for column number and division for a row number. Then I set that to a transform value and voila.
