EFootball Builder

Assumption-based tool for tactical planning in eFootball environments. Purpose is to enable data-driven lineup creation from roster data and formation templates. It supports scenario testing, training design, and pre-match tuning with explicit checks for role fit and positional coverage. It does not render UI, but provides structured outputs and export options for further analysis.
The core logic ingests a roster (player IDs, ratings, preferred foot, and role suitability) and a chosen formation (for example 4-3-3 or 3-5-2). It then computes a feasible allocation using a constraint-satisfaction approach augmented by a scoring model that weights defensive solidity, attacking potential, width, and pace. Outputs include the final lineup, justification per pick, and projected team metrics. Advanced options include fatigue weighting, opponent tendency consideration, and multiple lineup variants for comparison.
This tool benefits coaches, analysts, and players who need rapid, repeatable exploration of tactical options. Its unique value lies in combining formal constraint handling with tactical scoring, enabling quick iteration over dozens of formation and role permutations while preserving objective justification for each selection.
