Implement a smooth camera transition in Unreal Engine by animating the spring arm length with a timeline and keyframes from 300 to 150, wired into the event graph for aiming.

Clean up blueprints in a third-person Unreal Engine project by organizing input, aim, and attack systems, adjusting movement speed, and integrating attack animations with sword gameplay.

Set up a bow and arrow system in Unreal Engine by importing a skeleton with morph targets, adding idle and aiming animations, and wiring them in the character blueprint.

Set up the bow reload and shoot animation in bo mode with state transitions for aiming, reload, and arrow management, including recoil and four way movement via the actor component.

Create a bow animation in Unreal Engine using curves and keys, and trigger reload arrow and shoot arrow with an anim notify and blueprint interface.

Fix the arrow animation to prevent it sticking in the bow by adjusting frames and transitions, and create an arrow blueprint with projectile movement spawned when shooting.

Remove bow and arrow from the character, set up an aim offset with center, up, and down poses, and drive pitch from -90 to 90 using delta rotator.

Import a dummy and create a blueprint class actor dummy, then set up on damage to print the damage value and apply 35 damage on box collision overlap.

Create an aim crosshair and implement a line trace in blueprint to guide an arrow throw, spawning and moving the arrow toward impact location using camera and forward vector calculations.

Optimize bow and arrow animations for a mobile role-playing game in Unreal Engine by adjusting aim down sight, reload timing, bow scale, and switching arrow movement from eight-way to four-way.

Create a random punching attack by wiring three punch animations in the animation blueprint, using a random sequence player and a layer blend, with an animation notify to the blueprint.

Design a punching damage trace in Unreal Engine to create a responsive damage system for a mobile rpg game, using sphere traces, interfaces, and one-time damage via delays.

Import and rename sword attack animations, set up random sequence playback, and configure notifies and transitions to create varied sword attack capabilities in Unreal Engine.

Set up sword trace with right-hand start and end sockets, use capsule and sphere traces, detect hits on tick, and apply 35–50 damage after a 2-second delay.

Paste the sword trail particle into the content folder, reopen the Unreal Engine project, then add a notify tracker in the sword attack system and set start and end sockets.

Learn to optimize character movement by enforcing walk speed during aiming, disabling sprint, and toggling free mode when switching weapons in a bow and arrow system.

Set up a footstep sound system in unreal engine using six footstep sounds in walking SFX asset, triggered by animation notify and line trace to play at location with attenuation.

Create and assign jump and swinging sounds to a cube, then play and adjust volumes for the character sound system. Attach the bow with a delay to synchronize arrow audio.
