Types ¶
type Rand ¶
Rand is a PRNG resource to be used in [System] implementations.
This resource is provided by github.com/mlange-42/arche-model/model.Model per default.
Example ¶
package main
import (
"github.com/mlange-42/arche-model/model"
"github.com/mlange-42/arche-model/resource"
"github.com/mlange-42/arche/ecs"
"golang.org/x/exp/rand"
)
func main() {
m := model.New()
src := ecs.GetResource[resource.Rand](&m.World)
rng := rand.New(src.Source)
_ = rng.NormFloat64()
}
Output:
type SelectedEntity ¶ added in v0.2.0
SelectedEntity is a resource holding the currently selected entity.
The primarily purpose is communication between UI systems, e.g. for entity inspection or manipulation by the user.
Example ¶
package main
import (
"fmt"
"github.com/mlange-42/arche-model/model"
"github.com/mlange-42/arche-model/resource"
"github.com/mlange-42/arche/ecs"
)
func main() {
m := model.New()
ecs.AddResource(&m.World, &resource.SelectedEntity{})
sel := ecs.GetResource[resource.SelectedEntity](&m.World)
fmt.Println(sel.Selected.IsZero())
}
Output: true
type Termination ¶
type Termination struct {
Terminate bool // Whether the simulation run is finished. Can be set by systems.
}
Termination is a resource holding whether the simulation should terminate after the current step.
This resource is provided by github.com/mlange-42/arche-model/model.Model per default.
Example ¶
package main
import (
"fmt"
"github.com/mlange-42/arche-model/model"
"github.com/mlange-42/arche-model/resource"
"github.com/mlange-42/arche/ecs"
)
func main() {
m := model.New()
term := ecs.GetResource[resource.Termination](&m.World)
fmt.Println(term.Terminate)
}
Output: false
type Tick ¶
type Tick struct {
Tick int64 // The current model tick.
}
Tick is a resource holding the model's time step.
This resource is provided by github.com/mlange-42/arche-model/model.Model per default.
Example ¶
package main
import (
"fmt"
"github.com/mlange-42/arche-model/model"
"github.com/mlange-42/arche-model/resource"
"github.com/mlange-42/arche/ecs"
)
func main() {
m := model.New()
tick := ecs.GetResource[resource.Tick](&m.World)
fmt.Println(tick.Tick)
}
Output: 0
