Metal Slug demo: explosion VFX and a bomber enemy - #22
Merged
Conversation
- Sphere hazard now spawns a black explosion particle effect (via a new generic Spritesheet tint feature) when it detonates instead of just disappearing; the VFX is its own short-lived entity that cleans itself up once the one-shot animation finishes. - New stationary "enemy_bomber" enemy (on platform_1) lobs the existing sphere_prototype bomb at the player along a computed parabolic arc, reusing the same bomb/explosion chain as the falling-sphere hazard. This needed two small generic engine additions: a script-facing engine.get_entity_position(name, axis) query, and spawnEntity's optional vel_x/vel_y payload keys to launch a spawned clone with an initial velocity. - enemy_bomber tracks and faces the player every frame, and only plays its attack animation while a shot is firing (idle otherwise).
