Camera
VtTopDownCamera is a fixed-pitch follow camera with zoom, edge scrolling and middle-mouse panning.
See it running: the 01 · Hello Unit demo scene. See Demos to import the scenes.
Every field, its default and every member you can call: Camera reference.
Setup
- Add Vantage → Camera → VtTopDownCamera to the main camera.
- Drag the player into Initial Target, or call
SetTargetfrom your spawn code. - Make sure the scene has an Event System. The camera uses it to ignore scroll input over UI.
| Setting | Meaning |
|---|---|
| Pitch | Downward angle. 58 degrees is a classic RTS view. |
| Default / Min / Max Height | Starting zoom and its limits. |
| Enable Zoom, Zoom Speed | Scroll-wheel zoom. |
| Enable Edge Scroll, Edge Scroll Speed, Border | Pan when the mouse sits near the window edge. |
| Enable Middle Mouse Pan, Pan Speed | Drag with the middle button. |
| Snap Back Action | Re-centres on the target. Empty uses the Camera Snap Back action: Space, or the right stick press. See Input. |
Edge scrolling and panning detach the camera into free mode. IsInFreeCameraMode tells you which mode it is in. FocusOn(point) moves the camera to a point in free mode, as control groups do on a double tap; snapping back returns to the target.
Sharing the scroll wheel
If another system needs the wheel for a moment, hold it. VtBuildInput does this while it rotates a build ghost.
VtTopDownCamera.HoldScroll(this); // the wheel no longer zooms
VtTopDownCamera.ReleaseScroll(this); // zoom returns when the last holder lets goVtTopDownCamera.IsScrollBlocked still takes a predicate of your own, and IsScrollHeld answers whether anything holds the wheel.
The camera uses the Input System package only.
