How to Create Custom Maps with Jomho SRPG EditorCreating custom maps for strategy role-playing games can transform a good scenario into a memorable one. The Jomho SRPG Editor is a powerful, user-friendly tool designed specifically for creating tactical maps, events, and scripted encounters. This guide walks you through the entire process: planning your map, setting up the editor, building terrain, placing units and objects, configuring events and triggers, playtesting, and polishing for release.
Why custom maps matter
Custom maps let you design unique tactical challenges, tell stories through level design, and tailor pacing and difficulty for players. A well-crafted map balances terrain, objectives, and enemy placement to create emergent strategies and replayability.
Before you start: planning your map
- Define the concept: skirmish, defensive holdout, story-driven encounter, puzzle map, or boss arena.
- Determine the scale: small (10×10 tiles), medium (20×20), or large (40×40+). Smaller maps emphasize tactics and careful movement; larger maps reward maneuver and long-term planning.
- Draft objectives: defeat all enemies, capture a point, escort a unit, survive X turns, or trigger an event. Clear objectives keep playtesting focused.
- Sketch a rough layout on paper or a simple digital grid: chokepoints, open fields, hazards, elevation. Mark where the player and enemy will start.
Setting up Jomho SRPG Editor
- Install and open the editor. Familiarize yourself with the UI: main toolbar, tile palette, layer controls, unit and object placement panels, and event editor.
- Create a new map project and set the grid size to match your planned scale. Name and save the project immediately to avoid data loss.
- Configure general settings: tile size, default terrain types, fog of war, turn limits, and camera bounds if available.
Building terrain and environment
- Use layers: separate base terrain (ground tiles), height/elevation, decorative objects, and collision/impassable tiles. Layers make editing and iteration faster.
- Start with macro terrain: lay down large tiles for plains, forests, water, and mountains. Keep tile transitions natural—avoid abrupt, isolated tiles unless intentional.
- Create chokepoints and avenues of approach. Chokepoints funnel movement and create tension; open areas allow for flanking and cavalry charges.
- Add elevation and high-ground tiles sparingly. High ground should offer meaningful tactical advantage (range bonus, defensive buff).
- Place terrain hazards and features: rivers that require bridges, traps, mud that slows movement, or healing tiles. Balance risk vs. reward—rare, valuable resources should be guarded.
- Use decorative objects to give personality—ruins, trees, ruins, banners—but ensure they don’t obstruct readability or confuse navigation.
Example tile layer workflow:
- Base layer: ground tiles
- Elevation layer: cliffs/hills
- Collision layer: impassable rocks/walls
- Object layer: barrels, torches, trees
- Visual layer: ambient effects (fog, light)
Placing units and NPCs
- Start by placing your player units on one edge or in a defended position. Consider unit roles: tanks on frontlines, mages in mid-range, archers on high ground.
- Place enemy forces to match your map’s intended difficulty. Use mixed unit types to encourage varied tactics. For example, pair melee bruisers with ranged support and a fast flanker.
- Stagger reinforcements to prolong tension—set reinforcements to appear after a trigger, turn count, or when the player reaches a waypoint.
- Position neutral NPCs and civilians with care if they are objectives—ensure they’re reachable and their pathfinding won’t trap them.
- Set unit AI behavior (aggressive, defensive, stationary, patrol) to craft predictable or surprising enemy actions.
Tip: Use “mirror” placements for symmetrical maps to maintain balance in competitive scenarios.
Events, triggers, and scripting
- Events drive narrative and gameplay variety: cutscenes, reinforcements, dialogues, environmental changes, and victory/defeat conditions.
- Common trigger types: turn-based (on turn X), area-based (when a unit enters tile Y), unit death (when a boss dies), or item use.
- Keep event logic simple and testable. Complex chains are fine, but break them into smaller, named triggers for debugging.
- Example event flow: Player approaches shrine → trigger cinematic and dialogue → spawn enemy ambush → lock doors until ambush is cleared → open path and set new objective.
- Use variables to track state: hasRescuedNPC = true/false, bossPhase = 1/2/3. This lets events respond dynamically to player choices.
- Implement fail-safes: if a required unit gets stuck, provide a timeout or alternate path to prevent soft-locks.
Scripting tips and optimization
- Reuse scripts for common behaviors (patrol, guard, flanking) and call them with parameters for different units.
- Optimize performance by limiting active triggers and reducing unnecessary pathfinding calls for off-screen units.
- Keep event logs or debug messages enabled during testing so you can quickly trace why a trigger didn’t fire.
Playtesting and iteration
- Playtest early and often. Start with one solo run to verify basic flow, then have others test for blind-play perspectives.
- Test different playstyles: aggressive rush, cautious advance, ranged-only, and stealth (if applicable). Each reveals balance issues.
- Track issues: map exploits, unfair choke points, unreachable objectives, and performance drops. Prioritize fixes by severity.
- Iterate: adjust terrain, reposition units, tweak enemy stats or AI, and refine triggers. Small changes can significantly alter gameplay.
- Keep a changelog between playtests so you can revert or compare versions.
Balancing difficulty
- Use enemy composition, placement, and reinforcements to fine-tune challenge.
- Include safe recovery points or healing items if the map is long.
- Scale enemy stats or numbers across player progression to maintain challenge without feeling unfair.
- Provide alternate routes for weaker parties—multiple viable strategies increase player agency.
Polish: visuals, audio, and UX
- Add visual cues for objectives (flags, glowing tiles) and clearly label interactive objects. Players should never be confused about win conditions.
- Use ambient sound and music loops to set mood—battle music for enemy strongholds, ominous tones for boss arenas.
- Add short, readable dialogues and camera pans for key moments; avoid overly long cinematics that disrupt pacing.
- Include a difficulty indicator or recommended party level on the map’s loading screen.
Packaging and sharing your map
- Clean up unused assets and compress large files.
- Include a README: map concept, recommended party level/size, objectives, and known issues.
- If supported, add metadata tags (difficulty, size, recommended playtime) to help players find your map.
- Test loading/saving on a fresh profile to ensure no hidden dependencies on your development environment.
Common pitfalls and how to avoid them
- Overcomplication: too many triggers or mechanics can confuse players—prioritize clarity.
- Poor readability: cluttered visuals or similar-looking tiles make navigation hard—use contrast and clear icons.
- Soft-locks: ensure critical NPCs and objects have fail-safes or multiple access routes.
- Unbalanced encounters: playtest with diverse party builds and tweak accordingly.
Quick checklist before release
- Objectives are clear and reachable.
- No unreachable tiles/units.
- Events trigger reliably and have debug logs.
- Performance is stable on target hardware.
- README and metadata included.
Creating memorable maps in Jomho SRPG Editor is a cycle of design, build, test, and polish. Start small, iterate quickly, and focus on clarity of objectives and player experience. Happy mapmaking.
