systems, debuggers, visualizers, profilers, linkers, custom in-house tools, test infrastructure, contract handling infrastructure, … When you have a compiler, groovy! That’s step 1 of ~100 to real world

Design choices depend on: ▪ Budget / Game size & scope ▪ Studio size, Team experience ▪ Existing infrastructure & technology 6Range of designs ▶ Minimal extreme No building - game reads loose files on disk 19Presenting GridCache - alternative data structure for fast 3D lookups Created this when developing infrastructure to build a large city Have seen similar things - but nothing like this Can think of it as sparse

We need a parser/generator • Generate “ideal” interfaces and implementations • Have a tools infrastructure based on generation • Here, I’ll concentrate on C++ • We can also generate Java and Python

but that’s just one of Valgrind’s many capabilities. The true feat of Valgrind is its tooling infrastructure: it lets you write JiT manipulations without having to write a JiT compiler.JavaScript Identifies
