Unreal Survival #26 - Runtime placed object persistence

In this episode of the unreal engine survival series, I am going to implement a system to save the runtime placed plants save and load in the next session when player restart the game. As we have already implemented a system to place plants such as fruits/crops, after player saving the game, we should restore those runtime planted objects when player start the game next time. With the state of the plant. Here the state mean properties such as harvest growth level. This part is necessary to im...

Unreal Engine Double Jump Tutorial

In this tutorial, I am going to show you how to implement a double jump mechanism in unreal engine. In the default third person character we already have a jump mechanism. I am going to add a double jump to that. Which means when the character has jump once and already in the air, if player press jump button again, character will do another jump. This will allow character to reach higher places.

Rendering 3D character on UI - Unreal Open World #420

In this episode of unreal engine open world series, I am going to show you how to render the 3d player character which we use as the player character in the game on top of UI. I need this feature for the inventory menu I am working on. According to the design, when I open up the inventory, I need my character to show up in the middle of the screen. SO, in order to make it happen, I need to mask all other stuff in the scene and keep only the character visible. I am going to use a post process ...

Landscape Deformation in Unreal Engine II - Snow Deformation

Previously in Landscape Deformation Tutorial Part 1, we setup a landscape with a snow material and also added a function to place footprints of the third person character by deforming the landscape. Today, we are going to add some improvements to this system to get more realistic results with the deformation and footprints by changing the shape and material of the footprint object that writes to the runtime virtual texture output which allows us to deform the landscape in the runtime of the g...

For now I am going to toggle the visibility of the sk...

Unreal Falling flat and Getting up

Today, I am going to research of how to implement a character to fall flat on the ground when took off from a higher place and then get up. So, for this, we will need 3 separate animations falling (loopable) animation, and fall flat on ground, then get up part. The reason to have a loopable animation for the falling is character can fall from different heights and therefore, we should be able to play that part until the character hits the ground.  As I am using the rootmotion based locom...

Unreal Hand To Hand Combat - Replacing Mannequin with Actual Game Characters

Last time we implemented a hand to hand combat system with finisher moves which plays coordinated animations between 2 characters in order to get a choreographed cinematic look for the finisher attacks. But last time we implemented the system with the unreal mannequin character. Today I am going to import few other character models from marketplace and replace them in place of mannequin. So, for the player character, there will be a realistic looking character mesh and the enemies will have c...

Landscape color blending with Runtime Virtual Textures

Today I am going to show you how to use runtime virtual textures to blend grass and other object meshes to blend properly with the color of the landscape. We implemented something similar in Fortnite style grass rendering video I did here (https://youtu.be/I0S0Aufq5Ko) but there, the color map of the landscape was generated manually. We can automate that process with the runtime virtual textures. Basically what happens here...

Unreal Skateboarding #8 - Grind Direction

In the last episode of the skateboarding system, we implemented a grinding mechanism for the player to grind on objects like rails and curbs. But it has few issues such as player can enter the grinding object only from one direction and can move along the forward of the grinding object spline. Also when the character reach the grinding object faster, the grind star happens with a snap back along the spline. We are going to fix those issues and further improve the skateboarding system today. 2020-11-14 20:03:33 +0000 UTC View Post
