How to Build Motion Trail Effects in Godot 4 Using Ghost Sprites

0
·1 views

A tutorial published on DEV Community outlines a method for creating motion trail and afterimage effects in the Godot 4 game engine. The technique works by spawning fading ghost copies of a character sprite at timed intervals, each placed in world space so they remain fixed as the character moves. Developers create a self-destructing TrailGhost scene and a Trail node that activates and deactivates around movement events like dashes. The system supports customization options including tint colors, z-index layering, and speed-based activation for genres like racing or bullet-hell games. A ready-made plugin called Saltmire Trail is also mentioned for those who prefer a drop-in solution.

How Enterprises Can Build Reliable AI Agentic Workflows With Proper Controls

Agentic workflows, where AI systems execute multi-step tasks rather than responding to single prompts, are gaining traction as an enterprise automation approach. Unlike simple AI features, these workflows combine instructions, business data, tools, and human approval steps to move structured work forward. Experts recommend starting with a narrow, well-defined process that has a clear owner, a known bottleneck, and a measurable outcome, rather than broad mandates like automating entire departments. Governance must be embedded within the workflow itself, covering data access, identity management, human escalation, and incident response before any pilot scales to critical operations. Return on investment should be evaluated against a documented baseline, with oversight levels calibrated to the potential business impact of each workflow.

How to Add Directory Categories Without Breaking Ranked URLs

Expanding a web directory by adding new categories risks renaming existing URLs that already rank in search engines, which can cause lasting SEO damage even with 301 redirects in place. Developers are advised to preserve existing top-level URL paths and introduce new categories as separate routes, sharing logic through a common resolver function rather than restructuring the entire URL schema. A canonical redirect guard can automatically convert stale or mismatched URLs into 301 redirects, preventing 404 errors from old links or sitemap entries. New category pages should only go public once they meet a minimum inventory threshold, avoiding the indexing of thin, low-value content. The recommended rollout sequence is to add the category internally, seed listings, enable the route once populated, then add it to navigation and the sitemap before submitting URLs for crawling.

New SDK lets developers mint Algorand NFTs with IPFS metadata without Pinata

A new open-source SDK called ipfs-pay-to-pin-client allows developers to create NFTs on the Algorand MainNet blockchain without needing a Pinata account, API key, or subscription. The tool pins NFT metadata to IPFS using an automated micropayment system powered by USDC on the Algorand network, following the x402 payment protocol. Metadata pinning comes with a 365-day retention period per payment, with early renewal options available. Developers can mint Algorand Standard Assets with on-chain IPFS references by installing two Python packages and running a provided script. The workflow covers metadata creation, IPFS pinning via a pay-to-pin gateway, and ASA creation on MainNet in a single automated process.
