Changes to the starters of #1076, to merge into its branch (Starter-Submission-FPS-With-Enemies-And-Camera-Switching). The branch started at the former head of #1076 (8c58260f); the rewritten #1076 branch, rebased on the latest main, is merged in, so the diff only has the commits below.

The enemies of the FPS with enemies walk with a navmesh

The enemies used the grid pathfinding, with invisible obstacles (PathfindingObstacle) along the platform. They now walk with navmesh pathfinding (NavMeshPathfinding). The navmesh is built from:

• the ground, the platform and its ramps, which are walked on;
• the pushable boxes, which are only obstacles (the navmesh follows them when they are pushed).

The state machine is unchanged, and so are the vision raycast and the restart when an enemy collides with the player:

• Patrolling: the enemies walk to the player, or to a random place, on the navmesh. A random point near the player is at the height of the player, who can be on the platform; a random point inside the ground box is on the ground.
• Chasing: the enemies run to the player on the navmesh too, instead of being pushed toward the player with forces. So they go up a ramp to reach the player on the platform. The path is only updated when the player moves away from where it ends. Updated twice per second, the path kept switching between the two ramps (both about as far away), and the enemy went back and forth behind the platform.
• Physics body: while the navmesh moves an enemy, its physics body is kinematic: the player bumps into it without pushing it, and touching the player is the collision of the physics bodies, as in the submission.
• Shot: as in the submission, a shot enemy is thrown back by the impulse at the impact, and tumbles: the new "Body type" action of the 3D physics (Add an action to change the body type of 3D physics objects 4ian/GDevelop#9270, merged) makes its body dynamic right before the impulse.

The invisible obstacles and their texture are removed.

The "Body type" action needs GDevelop 5.6.285 (the release after 5.6.284): an older GDevelop doesn't know it and would skip it, and a shot enemy wouldn't be thrown. So the database now asks for GDevelop 5.6.285 or later for the examples using it (scripts/lib/ExampleGDevelopVersion.js, instead of 5.5.220 or later for the other 3D physics examples): an older GDevelop shows "Download the latest version of GDevelop to check out this example!". The gameplay tests of the CI use the latest build of GDevelop's master, which has the action (built at 14:52 UTC on 2026-10-20).

Before the action was available, the enemies used a dynamic body without gravity, without the collisions with the static objects and 100 times heavier, whose settings were restored, and the behavior deactivated and activated again, before the impulse: this is replaced by the action.

Theme slots

Both starters get a theme-slots.json, and every theme applies to both (checked with checkStarterThemeSlots and applyThemeToStarter):

• FPS with enemies: like the FPS starter (ground, walls and obstacles, pushable boxes, gun, sky), with the enemies as character.enemy.
• Camera monitoring: the walls (env.wall), the tiled floor (env.ground.tiled) and the furniture (env.crate, as it uses the texture of the pushable boxes of the other starters). The security cameras, the glass, the room areas and the light placeholders keep their look.

Also

• The skybox of the FPS with enemies uses the standard cube orientation, like the other starters (Update examples skyboxes direction to be standard cube #1069): the same images as the FPS starter, and "top": "Z+".
• The FPS with enemies gets its own project UUID. It had the one of the FPS horror starter.
• The ground, the walls and the pushable boxes of the FPS with enemies are in a World folder.
• The extensions of the FPS with enemies are updated to their latest versions: SpriteMultitouchJoystick 1.9.2, MousePointerLock 0.3.1, ParticleEmitter3D 3.2.1.
• The README of the FPS with enemies is one paragraph describing the game, the enemies and the gun included: its first paragraph is the description the AI uses to choose a starter.
• The events of both starters are unfolded, except the groups (which can stay folded).

Tests

Three tests are added to the FPS with enemies:

• a shot enemy is thrown back by the impact and tumbles;
• a patrolling enemy walks toward the player;
• an enemy that sees the player chases and catches them (the collision of the physics bodies restarts the scene).

They test what a game made from the starter keeps. They don't check how the physics body is set (kinematic while walking, dynamic when shot) or the height of an enemy above the ground. A test of an enemy going up a ramp to the platform was removed, since a game will change the level.

The two tests of the submission get a 120 s timeout: they render at 1280×720, which takes about a minute in the software renderer (60 s was just too short on a slower machine). All 5 tests pass with node scripts/run-gameplay-tests.js and the latest build of GDevelop's master (the one the CI uses). Checked apart: walking into a standing enemy, the player is stopped. ExampleGDevelopVersion.spec.js checks the version asked for an example using the action (in a scene or in an extension), and for the other examples; jest, tsc and prettier pass.

The two tests of the camera monitoring starter get a 120 s timeout: they timed out on CircleCI (35 to 50 s for their 170 frames, against the default 30 s). They render at 1280×720 with a spot light casting shadows and the CRT and glow effects of the camera view, which are slow in the software renderer of the CI. Both pass.

The "3D FPS with enemies Expanded" of #1087 is built from this version of the starter.
